data-annotations 2.6.0

Annotate data artifacts with provenance and descriptions

data-annotations

A Python package for attaching provenance and structured descriptions to the files and directories your workflows produce.

It is designed for lightweight research and reproducibility pipelines where you want generated datasets, tables, plots, or reports to carry enough context to explain where they came from and what they contain.

The package captures common provenance automatically and writes plain JSON and Markdown artifacts that are easy to inspect or archive. The canonical on-disk format uses one JSON annotation document per artifact:

• Files use artifact.ext.annotation.json
• Directories carry data-annotations.json at their root

Each annotation document stores four top-level sections:

• annotation_version
• subject
• provenance
• description

Here's the mental model: files get a visible sibling annotation, and directories carry one visible annotation at their root. Treat the annotation as part of the research output bundle.

See the changelog for release history and upgrade-oriented notes.

Installation

Install the core library from PyPI with pip:

pip install data-annotations

Or add it to a project with uv:

uv add data-annotations

The command-line interface uses optional dependencies. Install the package with CLI support when you want to run data-annotations commands:

pip install "data-annotations[cli]"
uv add "data-annotations[cli]"

For development or unreleased source installs, install directly from GitLab:

uv add "data-annotations @ git+https://gitlab.com/ceda-unibas/tools/data-annotations.git"
pip install "data-annotations @ git+https://gitlab.com/ceda-unibas/tools/data-annotations.git"

Pin a source install to a particular release tag x.y.z with:

uv add "data-annotations @ git+https://gitlab.com/ceda-unibas/tools/data-annotations.git@x.y.z"

What gets captured automatically

Every annotation document includes provenance with:

• A UTC creation timestamp
• Hostname and username
• The script path and command-line arguments
• The script path relative to the Git repo root when it can be determined
• Git commit, branch, dirty state, canonical repository remote, exact tags, and git describe output when available
• A source-code reference for recovery, derived from Git metadata when possible or supplied explicitly for archives, individual files, and DOI/URI records
• The current SLURM_JOB_ID when available
• Structured snapshots for recorded local inputs, including file checksums, directory content digests, and upstream annotation sidecar references when present

Local file hashing defaults to checksum policy auto: existing files are hashed only up to 10 * 1024**3 bytes (10 GiB). Larger files are still recorded, but their sha256 or directory content_digest is left unset unless you provide a precomputed checksum yourself.

You can also attach your own parameters, input file paths, and function names. Local filesystem paths in provenance are stored as absolute paths. URI-style inputs such as s3://... or https://... are preserved as provided. Git tags and git_describe are human-friendly hints only. For Git sources, git_sha and source_code.revision identify the recoverable code state.

Quick Start

The recommended way to annotate your data artifacts is to decorate pipeline functions that consume some inputs and parameters, then write those artifacts. This keeps the artifact-writing logic explicit while letting data-annotations capture provenance and emit sidecars automatically.

For example, here is a complete file-level annotation workflow using the record_file_annotation(...) decorator. Once write_participants is called, it automatically generates sidecars participants.csv.annotation.json and participants.csv.README.md. The JSON sidecar will contain provenance and description metadata, and the Markdown sidecar will have a human-friendly rendering of the description provided in the decorator.

from pathlib import Path

from data_annotations.annotations import record_file_annotation
from data_annotations.description import AllowedValue, FieldDefinition

@record_file_annotation(
    title="Participant Cohort",
    summary="Participant-level cohort assignments for the validation split.",
    fields=[
        FieldDefinition(
            name="participant_id",
            data_type="string",
            summary="Stable participant identifier.",
            required=True,
            nullable=False,

                AllowedValue(value="control"),

)
def write_participants(
    artifact_path: Path,
    input_path: Path,
    split: str,
) -> Path:
    participant_ids = [
        line.strip()
        for line in input_path.read_text(encoding="utf-8").splitlines()[1:]
        if line.strip()
    ]
    artifact_path.parent.mkdir(parents=True, exist_ok=True)
    artifact_path.write_text(
        "\n".join(
            [
                "participant_id,group,split",
                *[
                    f"{participant_id},control,{split}"
                    for participant_id in participant_ids
                ],
            ]
        )
        + "\n",
        encoding="utf-8",
    )
    return artifact_path

# Annotation sidecars are written automatically
# when the decorated function is called:
artifact_path = Path("outputs") / "participants.csv"
write_participants(
    artifact_path=artifact_path,
    input_path=Path("data/raw/participants.csv"),
    split="validation",
)

print(f"{artifact_path}.annotation.json")
print(f"{artifact_path}.README.md")

Decorator Contract

You write a normal Python function and the decorator returns that function's original return value unchanged.

For provenance-bearing decorators, recorded inputs are inferred from named function arguments such as input_path and input_paths. Those arguments should correspond to real data dependencies used inside the wrapped function.

For file decorators:

• record_file_manifest(...)
• record_file_annotation(...)
• record_file_description(...)

Your function should:

• accept one argument pointing at the output file path. By default this argument is named artifact_path, but you can change the expected name with artifact_path_arg=....
• use any other normal Python arguments you need for the pipeline step.
• for provenance-bearing decorators, use argument names listed in input_args for real upstream dependencies you want recorded as provenance inputs. By default those names are ("input_path", "input_paths").

Your function may return any value. File decorators do not inspect that return value. Returning the generated artifact_path is recommended because it is convenient for callers, but it is not required.

For directory decorators:

• record_directory_manifest(...)
• record_directory_annotation(...)
• record_directory_description(...)

Your function should:

• accept one argument pointing at the output directory. By default this argument is named output_dir, but you can change the expected name with output_dir_arg=....
• return a materialized iterable, usually a list, describing the files that were produced in that directory.
• prefer returning a list or tuple rather than a generator, since the decorator needs to iterate over the outputs to write sidecars.

Accepted directory return items are:

• DocumentedArtifact when you want per-artifact title, summary, fields, keys, or missing-value metadata.
• DocumentedArtifactGroup for record_directory_annotation(...) and record_directory_description(...) when many files share one title, summary, kind, and optional schema metadata.
• ProducedFile when you only need path, kind, and optional precomputed hash.
• ChildBundle when an annotated child directory should be referenced as its own independently shareable bundle.
• (path, kind) tuples when path and artifact kind are enough.
• plain path-like values when the artifact kind can default to "other".

For provenance-bearing directory decorators, input_args works the same way as for file decorators: matching argument names are recorded as inputs, and the remaining bound arguments become provenance params.

Here is another decorator pattern example with record_directory_annotation(...):

from pathlib import Path

from data_annotations.annotations import record_directory_annotation
from data_annotations.description import (
    DocumentedArtifact,
    DocumentedArtifactGroup,
    FieldDefinition,
)
from data_annotations.provenance import ProducedFile

@record_directory_annotation(
    title="Validation Outputs",
    summary="Directory-level documentation for the validation run outputs.",
    acquisition_context={"source": "Study A registry export"},
    generation_context={"pipeline": "baseline-v1"},
)
def build_outputs(
    output_dir: Path,
    input_path: Path,
    split: str,
):
    participant_ids = [
        line.strip()
        for line in input_path.read_text(encoding="utf-8").splitlines()[1:]
        if line.strip()
    ]
    output_dir.mkdir(parents=True, exist_ok=True)

    table_path = output_dir / "scores.csv"
    table_path.write_text(
        "\n".join(
            [
                "participant_id,score,split",
                *[
                    f"{participant_id},0.94,{split}"
                    for participant_id in participant_ids
                ],
            ]
        )
        + "\n",
        encoding="utf-8",
    )

    report_path = output_dir / "summary.txt"
    report_path.write_text(
        (
            f"Validated {len(participant_ids)} participants from "
            f"{input_path.name} for the {split} split.\n"
        ),
        encoding="utf-8",
    )

    plot_paths = []
    for day in ["2024-01-01", "2024-01-02", "2024-01-03"]:
        plot_path = output_dir / f"sma_{day}.png"
        plot_path.write_bytes(
            (
                f"plot placeholder for the SMA variable on {day}, "
                f"derived from {input_path.name}\n"
            ).encode("utf-8")
        )
        plot_paths.append(plot_path)

    return [
        DocumentedArtifact(
            path=str(table_path),
            kind="dataset",
            title="Metrics Table",
            fields=[
                FieldDefinition(
                    name="metric",
                    data_type="string",
                    summary="Metric name.",
                ),
                FieldDefinition(
                    name="value",
                    data_type="float",
                    summary="Metric value.",
                ),
            ],
        ),
        ProducedFile(path=str(report_path), kind="report"),
        DocumentedArtifactGroup(
            title="Daily SMA plots",
            summary="Plots of the same variable on different days.",
            kind="plot",
            paths=[str(path) for path in plot_paths],
            selector="sma_*.png",
        ),
    ]


output_dir = Path("outputs") / "run-001"
build_outputs(
    output_dir=output_dir,
    input_path=Path("data/raw/participants.csv"),
    split="validation",
)

print(output_dir / "data-annotations.json")
print(output_dir / "README.md")

The decorator and direct APIs write the same canonical document shape. If you need metadata to vary per call instead of staying fixed at decoration time, use annotate_file(...), annotate_directory(...), write_file_annotation(...), or write_directory_annotation(...) directly instead. See the example gallery in examples/ for runnable examples of all approaches.

When To Use Decorators Vs Direct Functions

If a function is only a final serializer for already-prepared data, prefer the direct annotation and writer APIs. They let you attach inputs=[...] explicitly.

Canonical Document Shape

File annotations store:

• subject.path
• subject.kind
• subject.sha256
• provenance.*
• provenance.input_artifacts[]
• description.title
• description.summary
• description.fields
• description.primary_key
• description.missing_value_codes
• description.acquisition_context
• description.generation_context
• description.description_updated_at

Directory annotations store:

• subject.path
• subject.produced_files[]
• subject.child_bundles[]
• subject.content_digest
• provenance.*
• provenance.input_artifacts[]
• description.title
• description.summary
• description.artifact_groups[]
• description.artifacts[]
• description.acquisition_context
• description.generation_context
• description.description_updated_at

Use description.artifact_groups[] when many files have the same meaning, and use description.artifacts[] only for file-specific notes, overrides, or schema. Groups are descriptive only. Integrity still lives in subject.produced_files[], which tracks every concrete file by path, kind, and checksum.

The description section intentionally excludes provenance linkage fields. Directory produced_files[].path values are stored relative to subject.path, which keeps verification stable when a complete output directory is copied or archived elsewhere. subject.content_digest is computed from sorted tracked file paths, file checksums, and referenced child bundle digests.

Artifact Groups

Artifact groups are for homogeneous sets of files that researchers naturally understand as one output family: for example, 100 PNG plots of the same variable, one per acquisition day. A group stores the shared title, summary, kind, optional schema fields, and the concrete member paths. It can also store an informational selector, such as plots/*.png, to show how the group was chosen.

Rules of thumb:

• Use artifact groups when many files have the same meaning.
• Use individual artifacts for file-specific notes, exceptions, or overrides.
• It is OK for an individual artifact to also appear in a group.
• Do not rely on groups for integrity. subject.produced_files[] remains the complete checksum inventory.

Nested Directory Policy

Annotate the smallest thing you would share as a unit. If a directory is one research output, give that directory one data-annotations.json, even when its tracked files live in nested subdirectories.

Use recursive directory annotations for one bundle with nested files:

data-annotations annotate directory path/to/run-001 --recursive
data-annotations annotate directory path/to/run-001 --max-depth 2

Use child bundle annotations when a subdirectory is independently meaningful, shareable, or reusable. In that case, annotate the child directory first, then annotate the parent. The parent records a compact child_bundles[] reference with the child path, child annotation path, and child content digest; it does not copy the child file inventory into the parent JSON.

Post-hoc directory discovery follows the same rule. --recursive discovers nested files, but it stops at annotated child directories containing data-annotations.json and records them as child bundles.

Provenance Decorators And Writers

The data_annotations.provenance namespace provides provenance-only entry points. Prefer the decorators when you already have a small function that writes artifacts:

from pathlib import Path

from data_annotations.provenance import record_file_manifest


@record_file_manifest(artifact_kind="report")
def write_report(
    artifact_path: Path,
    input_path: Path,
    threshold: float = 0.5,
):
    artifact_path.parent.mkdir(parents=True, exist_ok=True)
    artifact_path.write_text(
        f"threshold applied: {threshold}\nsource={input_path.name}\n",
        encoding="utf-8",
    )


write_report(
    artifact_path=Path("outputs/summary.txt"),
    input_path=Path("data/raw/participants.csv"),
    threshold=0.75,
)

Use record_directory_manifest(...) for directory outputs. Directory decorators accept DocumentedArtifact, ProducedFile, (path, kind), and plain path-like return values. Provenance-only APIs do not accept description groups; use unified annotation or description APIs when groups should appear in the JSON or README.

If you want the direct writer approach instead, use write_file_manifest(...) and write_directory_manifest(...) (see examples/).

Checksum Policy

All provenance and annotation entry points that hash local files support the same policy controls:

• checksum_policy="auto": hash existing local files only when they are at or below max_checksum_bytes. This is the default, and max_checksum_bytes defaults to 10 * 1024**3 bytes (10 GiB).
• checksum_policy="always": hash existing local files regardless of size.
• checksum_policy="never": never hash local files automatically. Checksums are recorded only when you supply them explicitly.

When a checksum is skipped, JSON sidecars keep the same schema and simply store sha256: null. Directory content_digest is also left unset when any tracked member file lacks a checksum.

You can change the policy from Python:

from data_annotations.annotations import annotate_file
from data_annotations.provenance import write_file_manifest

write_file_manifest(
    "outputs/summary.txt",
    checksum_policy="always",
)

annotate_file(
    "outputs/summary.txt",
    title="Run Summary",
    summary="Post-hoc summary.",
    artifact_sha256="precomputed-sha256",
    checksum_policy="never",
)

You can also inject precomputed checksums directly:

• File APIs: pass artifact_sha256=....
• File or directory APIs: pass checksum_overrides={path: sha256}. For directory outputs, keys can be relative to the output directory or absolute paths.
• Decorators such as record_file_manifest(...), record_directory_manifest(...), record_file_annotation(...), and record_directory_annotation(...) accept the same checksum-policy arguments.

From the CLI, use --checksum-policy, --max-checksum-bytes, --sha256, and repeatable --checksum PATH=SHA256:

data-annotations annotate file path/to/summary.txt \
  --title "Run Summary" \
  --summary "Post-hoc summary." \
  --kind report \
  --checksum-policy never \
  --sha256 0123456789abcdef...

data-annotations annotate directory path/to/run-001 \
  --title "Processing outputs" \
  --summary "Directory-level outputs." \
  --checksum-policy never \
  --checksum processed.csv=0123456789abcdef...

data-annotations provenance chain path/to/run-001 \
  --checksum-policy always

For a complete runnable workflow, see examples/checksum_policy.py.

Description Layer

The data_annotations.description sub-package provides the structured description models used by annotation writers and the Markdown sidecar renderers. Within those models, the primary human-written narrative field is named summary.

Key public description models:

• AllowedValue
• FieldDefinition
• DocumentedArtifact
• DocumentedArtifactGroup
• ArtifactDescription
• ArtifactGroupDescription
• FileDescription
• DirectoryDescription

Description decorators and helpers:

• record_file_description(...)
• record_directory_description(...)
• write_file_description(...)
• write_directory_description(...)
• render_file_readme(...)
• render_directory_readme(...)

Alias helpers write_file_readme(...) and write_directory_readme(...) are supported.

Use the decorator forms when the description metadata is stable for a function, and use the direct helpers when you want to assemble descriptions per call.

Recovery Helpers

Use artifact_matches_manifest(...) to verify whether a detached artifact still matches an annotation document. Use analyze_provenance_chain(...) when you also want to verify recorded inputs and recursively follow upstream annotation sidecars. Use recover_manifest_source(...) to recover the recorded source code from Git metadata, a recorded source archive, or a recorded source file. checkout_manifest_source(...) remains available as a compatibility alias.

from pathlib import Path

from data_annotations.provenance import (
    analyze_provenance_chain,
    artifact_matches_manifest,
    recover_manifest_source,
)

annotation_path = Path("outputs/participants.csv.annotation.json")
artifact_path = Path("downloads/participants.csv")

if artifact_matches_manifest(artifact_path, annotation_path):
    chain = analyze_provenance_chain(artifact_path)
    print(chain.status)
    recovered = recover_manifest_source(annotation_path)
    print(recovered.checkout_path)
    print(recovered.script_path)

Post-Hoc Annotation

The strongest workflow is to create provenance and description at the same time as the artifact itself. When annotations are written during generation, the package can capture runtime context directly and the resulting records are typically more complete, precise, and trustworthy.

For existing artifacts, the CLI provides a post-hoc annotation path so you can still attach provenance and description after the fact.

Post-hoc descriptions can still be very useful, but the quality of post-hoc provenance depends on how exact the supplied answers are. In particular, fields such as the generating script, command, function, source-code URI, Git commit, repository path, Git tags, git describe output, inputs, and parameters are only as reliable as the information entered during annotation.

CLI Workflow

This package provides a command-line interface (CLI) for retrospective annotation and provenance inspection.

For post-hoc annotation:

data-annotations annotate file path/to/participants.csv
data-annotations annotate directory path/to/run-001
data-annotations annotate directory path/to/run-001 --recursive
data-annotations annotate directory path/to/run-001 --max-depth 2
data-annotations annotate directory path/to/run-001 \
  --recursive \
  --group-selector "plots/*.png" \
  --group-title "Daily SMA plots" \
  --group-summary "Plots of the same variable on different days." \
  --group-kind plot

These commands prompt for missing details, write *.annotation.json or data-annotations.json, and optionally derive README sidecars. Post-hoc records are marked with capture_mode="post_hoc".

For shell workflows, you can move the prompt answers into a YAML file and run the command non-interactively:

data-annotations annotate file path/to/participants.csv --answers participants.yaml
data-annotations annotate directory path/to/run-001 --answers run-001.yaml
data-annotations annotate answers check participants.yaml

When --answers is provided, --no-interactive is the default. Use --interactive if you want the YAML file to provide defaults and still prompt for missing required values. If the YAML file includes target, the positional target may be omitted; when both are provided, they must resolve to the same path. Environment variables such as $DATA_ROOT and ${DATA_ROOT} are expanded inside string values, and validation fails if a referenced variable is not set. The answers check helper requires target so it can infer whether the answers describe a file or a directory.

File answers can use top-level prompt-style keys:

target: path/to/participants.csv
title: Participant Cohort
summary: Participant-level cohort assignments.
kind: dataset
sha256: 0123456789abcdef...

inputs:
    - ${DATA_ROOT}/raw/participants.csv

params:
    split: validation

provenance:
    command: bash scripts/build_participants.sh
    script: scripts/build_participants.sh
    git_sha: deadbeef
    source_code:
        kind: archive
        uri: https://doi.org/10.5281/zenodo.12345
        download_uri: https://zenodo.org/records/12345/files/source.zip
        path: scripts/build_participants.sh
        sha256: 0000000000000000000000000000000000000000000000000000000000000000

fields:
    - name: participant_id
      summary: Stable participant identifier.
      data_type: string
      required: true
      nullable: false

primary_key:
    - participant_id

Directory answers use an explicit inventory. Paths in artifacts, artifact_groups.paths, and child_bundles are relative to the annotated directory unless absolute:

target: path/to/run-001
title: Processing outputs
summary: Files produced by the shell processing workflow.

provenance:
    command: bash process_from_instrument.sh
    script: process_from_instrument.sh

checksums:
    processed.csv: 0123456789abcdef...

artifacts:
    - path: processed.csv
      kind: dataset
      title: Processed instrument output
      summary: Normalized output from the processing script.

artifact_groups:
    - title: Diagnostic plots
      kind: plot
      selector: plots/*.png
      paths:
          - plots/qc-1.png
          - plots/qc-2.png

child_bundles:
    - path: model
      annotation_path: model/data-annotations.json

Answers files may also use schema-style aliases such as subject.path, subject.kind, description.title, description.summary, description.artifacts, description.artifact_groups, provenance.inputs, and provenance.params.

For source-code recovery, provenance.source_code.kind may be git, archive, file, or uri. Git sources use uri plus revision; archive and file sources use uri or download_uri plus an optional sha256; path points to the generating script inside the recovered source. DOI or landing-page-only references can be recorded with kind: uri, but they are not directly recoverable unless a direct archive or file download_uri is also recorded.

When group selectors are provided, the CLI expands them to concrete member paths at annotation time. Grouped files are tracked in subject.produced_files[] but are skipped by the per-file prompt flow, so you do not have to answer the same questions for every matching file.

For post-hoc provenance, use --source-kind, --source-uri, --source-download-uri, --source-path, --source-revision, and --source-sha256 when the generating code is recoverable from a Git remote, source archive, source file, or reference URI. Use repeatable --git-tag and optional --git-describe when you know the original Git state; these values are stored as human-readable hints.

For provenance inspection and source recovery:

data-annotations provenance match path/to/artifact
data-annotations provenance chain path/to/artifact
data-annotations provenance chain path/to/artifact --full-paths
data-annotations provenance checkout path/to/artifact

Command checkout recovers the recorded source code. For Git sources, it clones the recorded remote and checks out the recorded revision. For archive and file sources, it downloads or copies the recorded object, verifies sha256 when present, and resolves the generating script path when recorded. Reference-only URI sources are preserved in the annotation but are not directly recoverable. The command prompts before downloading source code and defaults to No; use --force when running trusted provenance checkout non-interactively.

Command match auto-discovers *.annotation.json for files and data-annotations.json for directories, prints a verification summary, and suggests the exact checkout command to run next when Git recovery metadata is available. Command chain uses the same sidecar discovery, then verifies the artifact, recorded input snapshots, and any upstream annotation sidecars reachable from those inputs. Its default output shows a compact relative-path tree and lists stale, missing, or unverifiable nodes first; use --full-paths when you need absolute paths.

For publication workflows, create a sanitized copy of an annotated artifact tree:

data-annotations publish path/to/run-001 path/to/publish-bundle
data-annotations publish path/to/run-001 path/to/publish-bundle \
  --prefix /private/raw/study-a='$INPUT_ROOT'
data-annotations publish path/to/run-001 path/to/publish-metadata \
  --annotations-only
data-annotations publish path/to/run-001 path/to/publish-bundle --dry-run

Command publish recursively discovers file annotations (*.annotation.json) and directory annotations (data-annotations.json), writes a mirrored publish bundle, and regenerates README sidecars from sanitized annotation JSON. Paths under the source directory are rewritten to $ARTIFACT_ROOT/...; additional --prefix mappings rewrite other private path roots. Hostname, username, and SLURM job ID are redacted by default. Git remote URLs are preserved unless --redact-git-remote is provided. Strict mode is enabled by default and fails if any local absolute path remains after sanitization; use --no-strict only after reviewing --dry-run output.

If data-annotations provenance --help does not list chain, your shell is resolving an older installed command. From a source checkout, use uv run data-annotations provenance chain ..., or reinstall the CLI from the updated source before using the bare data-annotations command.

Both match and chain also accept --checksum-policy and --max-checksum-bytes. Use --checksum-policy always when you want full verification of large local files, and leave the default auto when you prefer to avoid long checksum passes on very large artifacts.

Run With uvx

uvx --from "data-annotations[cli]" data-annotations provenance match path/to/participants.csv

Install And Use With uv tool

uv tool install "data-annotations[cli]"
data-annotations provenance match path/to/participants.csv

Run From Repository Root

From the repository root while developing locally, run task install first. That task uses uv sync --extra cli, so the CLI commands are available in the project environment. You can then run:

uv run data-annotations annotate file path/to/participants.csv
uv run data-annotations annotate directory path/to/run-001
uv run data-annotations provenance match path/to/participants.csv
uv run data-annotations provenance chain path/to/participants.csv
uv run data-annotations provenance checkout path/to/participants.csv
uv run data-annotations publish path/to/run-001 path/to/publish-bundle

Examples

Runnable examples live in examples/ and mirror the README workflows. Run them from the repository root with:

uv run python examples/record_file_annotation.py
uv run python examples/record_directory_annotation.py
uv run python examples/record_file_manifest.py
uv run python examples/record_directory_manifest.py
uv run python examples/record_file_description.py
uv run python examples/record_directory_description.py
uv run python examples/annotate_file.py
uv run python examples/annotate_directory.py
uv run python examples/checksum_policy.py
uv run python examples/annotate_file_answers_cli.py
uv run python examples/write_file_manifest.py
uv run python examples/write_directory_manifest.py
uv run python examples/write_file_description.py
uv run python examples/write_directory_description.py
uv run python examples/provenance_chain.py
uv run python examples/provenance_chain_cli.py
uv run python examples/recover_provenance.py
uv run python examples/recover_provenance_cli.py
uv run python examples/recover_archive_source.py
uv run python examples/publish_cli.py

Each example writes its outputs to a fresh temporary directory and prints the location so you can inspect the generated annotation documents and README sidecars.
