cvfile-haystack 0.2.0

Haystack integration for the .cv open file format.

cvfile-haystack

Haystack 2.x converter component for the .cv open file format.

A .cv file is a PDF/A-3u file carrying a Markdown copy of the same content (plus optional HTML and JSON Resume) as PDF Associated Files. Instead of OCR ing the PDF, this component reads the embedded text payloads directly and emits Haystack Document objects ready for indexing.

Install

pip install cvfile-haystack

Use

from haystack_integrations.components.converters.cvfile import CVFileToDocument

converter = CVFileToDocument()
result = converter.run(sources=["resume.cv"])
documents = result["documents"]

for doc in documents:
    print(doc.meta["payload"], doc.meta["mime_type"], len(doc.content))

You get one Document per textual payload found in the file. The Markdown copy (typically resume.md) is the one flagged with meta["primary"] = True.

Primary only

If you only want the canonical Markdown copy and want to skip language alternates and supplements:

converter = CVFileToDocument(primary_only=True)

Pipeline use

from haystack import Pipeline
from haystack.components.embedders import SentenceTransformersDocumentEmbedder
from haystack.components.writers import DocumentWriter
from haystack.document_stores.in_memory import InMemoryDocumentStore
from haystack_integrations.components.converters.cvfile import CVFileToDocument

store = InMemoryDocumentStore()
pipe = Pipeline()
pipe.add_component("read", CVFileToDocument(primary_only=True))
pipe.add_component("embed", SentenceTransformersDocumentEmbedder(model="BAAI/bge-m3"))
pipe.add_component("write", DocumentWriter(document_store=store))
pipe.connect("read.documents", "embed.documents")
pipe.connect("embed.documents", "write.documents")

pipe.run({"read": {"sources": ["resumes/jane.cv", "resumes/john.cv"]}})
