CLI tools for OLDAP

OLDAP tools

OLDAP tools is a CLI tool for managing parts of the OLDAP framework. It allows to

• dump all the data of a given project to a gzipped TriG file
• load a project from a gzipped TriG file created by oldap-tools
• load a hierarchical list from a YAML file
• dump a hierarchical list to a YAML file

Installation

The installation is done using pip: pip install oldap-tools

Usage

The CLI tool provides the following commands:

• oldap-tools project dump: Dump all the data of a given project to a gzipped TriG file
• oldap-tools project load: Load a project from a gzipped TriG file created by oldap-tools
• oldap-tools list dump: Dump a hierarchical list to a YAML file
• oldap-tools list load: Load a hierarchical list from a YAML file
• oldap-tools ontology validate: Validate an ontology datamodel YAML file
• oldap-tools ontology load: Load or update an ontology datamodel from YAML
• oldap-tools ontology dump: Dump an ontology datamodel to YAML or TriG

Common options

• --graphdb, -g: URL of the GraphDB server (default: "http://localhost:7200")
• --repo, -r: Name of the repository (default: "oldap")
• --user, -u: OLDAP user (required) which performs the operations
• --password -p: OLDAP password (required)
• --graphdb_user: GraphDB user (default: None). Not needed if GraphDB runs without athentification.
• --graphdb_password: GraphDB password (default: None). Not needed if GraphDB runs without athentification.
• --verbose, -v: Print more information

Command

Project dump

This command dumps all the data of a given project to a gzipped TriG file. It includes user information of all users associated with the project. The command has the following syntax (in addition to the common options):

oldap-tools [common_options] [graphdb-options] project dump [-out <filename>] [--data | --no-data] [-verbose] <project_id>

The graphdb options see above. The other options are defined as follows:

• -out <filename>: Name of the output file (default: "<project_id>.trig.gz")
• --data | --no-data: Include or exclude the data of the project (default: include)
• -verbose: Print more information
• <project_id>: Project identifier (project shortname)

The file is basically a dump of the project specific named graphs of the GraphDB repository. This are the following graphs:

• <project_id>:shacl: Contains all the SHACL shapes of the project
• <project_id>:onto: Contains all the OWL ontology information of the project
• <project_id>:lists: Contains all the hierarchical lists of the project
• <project_id>:data: Contains all the resources (instances) of the project

The user information is stored as special comment in the TriG file and is interpreted by oldap-tools project load.

Project load

This command loads a project from a gzipped TriG file created by oldap-tools. It has the following syntax (in addition to the common options):

oldap-tools [common_options] [graphdb-options] project load --i <filename>

The options are as follows:

• --inf, -i: Name of the input file (required)
• -verbose: Print more information

If a user does not exist, then the user is created. If the User is already existing, then the user is replaced.

NOTE: This will change in the future in order to only update project specific permissions to the existing user.

List dump

This command dumps a hierarchical list to a YAML file. This file can be edited to add/remove or change list items. The command has the following syntax (in addition to the common options):

oldap-tools [common_options] list dump [-out <filename>] <project_id> <list_id>

This command generates a YAML file which can be edited and contains the list and all it nodes

The options are as follows:

• -out , -o: Output file
• <project_id>: Project identifier (project shortname)
• <list_id>: List identifier

List load

This command loads a hierarchical list from a YAML file into the given project. The command has the following syntax (in addition to the common options):

oldap-tools [common_options] list load --inf <filename> <project_id>

The options are as follows:

• --inf, -i: Name of the input file (required)
• <project_id>: Project identifier (project shortname)

Ontology validate

This command validates an ontology YAML file against the bundled schema:

oldap-tools [common_options] ontology validate --inf <filename>

Ontology load

This command loads or updates a project datamodel from a YAML file:

oldap-tools [common_options] ontology load --inf <filename> [--mode update|replace] [--connectors create|replace] [--backup|--no-backup] [--backup-out <filename>]

By default, the command makes a TriG gzip backup of the model and list graphs before loading. The replace mode deletes the existing datamodel graphs (<project>:shacl and <project>:onto) and recreates them from YAML. The update mode compares the YAML classes and properties with the current datamodel and lets oldaplib perform the corresponding updates. Set an attribute to null in update mode to delete it, for example label, comment, name, description, min_count, or max_count.

Hierarchical lists can be referenced as external YAML files or defined inline. A property can point to a list node class with to_class: list:<ListId>.

Lucene connectors can be declared in the same YAML file. They are skipped by default and only applied when --connectors create or --connectors replace is passed. Single-property fields can use a QName directly and get their Lucene field name from the property fragment. Multi-step chains must be given an explicit Lucene field name.

Example:

ontology:
  project:
    shortname: fasnacht
    iri: https://fasnacht.digital
    namespace: http://fasnacht.digital/ns/
    start: 2025-06-01

  lists:
    CreativeCommons: CreativeCommons.yaml

  external_ontologies:
    schema:
      namespace: https://schema.org/
      label: schema.org
      proposedResourceClass:
        - Person
        - Organization

  classes:
    fasnacht:Person:
      label:
        en: Person
        de: Person
      superclass:
        - schema:Person
      properties:
        - iri: schema:familyName
          datatype: xsd:string
          name:
            en: Family name
            de: Nachname
          min_count: 1
          max_count: 1
          order: 1
          editor: TEXT_FIELD

  lucene_connectors:
    fasnacht:
      types:
        - fasnacht:Story
        - fasnacht:ArchiveObject
        - fasnacht:ArchiveMediaObject
      fields:
        - fasnacht:storyContent
        - schema:abstract
        - fasnacht:archiveObjectTitle
        - schema:description
        - fieldName: representedArchiveObjectTitle
          chain:
            - fasnacht:archiveMediaObjectOf
            - fasnacht:archiveObjectTitle

oldap-tools creates one GraphDB Lucene connector per project. The connector name is always the project short name. Multiple entries below lucene_connectors are treated as YAML grouping/specification blocks and are merged into that project connector.

Ontology dump

This command dumps an ontology datamodel either as YAML or as a TriG gzip file containing the <project>:shacl, <project>:onto, and <project>:lists graphs:

oldap-tools [common_options] ontology dump [-out <filename>] [--format yaml|trig] <project_id>
