Decision gist · record as of 2026-08-14
Yes, with conditions. The package has low install friction and no known vulnerabilities, making it technically safe to use. However, the original maintainer has retired and the package is now community-maintained with minimal activity (1 star, aging status, last commit in January 2026). Install it if you need RDFa 1.1 parsing and are comfortable with a stable but not actively developed library; verify the unclear license terms before use in commercial or restricted-license projects.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.8 or higher; requests 2.32.3 or higher, rdflib 7.0.0 or higher, and html5lib 1.1.
- Low install friction with three straightforward dependencies (requests, rdflib, html5lib).
- However, the original maintainer has stepped back and the package is now maintained by a community contributor; the repository is archived but not abandoned.

What it is and what it does
pyRdfa3 is a Python library that parses RDFa 1.1 markup embedded in HTML documents and distills it into structured RDF data. It reads HTML files or web pages containing RDFa annotations—semantic metadata embedded as HTML attributes—and extracts the underlying RDF triples, which can then be queried or manipulated using rdflib.
The package is built on three core dependencies: requests for fetching remote HTML, rdflib for representing and working with RDF graphs, and html5lib for robust HTML parsing. It supports Python 3.8 and higher and is designed for developers working with semantic web standards, linked data, or applications that need to extract structured metadata from web pages.
Use it for
- Extract structured data from web pages marked up with RDFa to build knowledge graphs or semantic search indexes.
- Convert RDFa-annotated HTML documents into RDF/Turtle or other RDF serialization formats for downstream processing.
- Validate or test RDFa markup compliance in HTML documents against the RDFa 1.1 specification.
- Integrate semantic web data extraction into data pipelines that consume linked data from third-party websites.
- Build tools that harvest schema.org or other RDFa vocabularies from HTML to populate databases or ontologies.

Before you install
Low install friction with three straightforward dependencies (requests, rdflib, html5lib). However, the original maintainer has stepped back and the package is now maintained by a community contributor; the repository is archived but not abandoned. Last commit was recent, but the aging status and low star count suggest limited active development.
Requires Python 3.8 or higher; requests 2.32.3 or higher, rdflib 7.0.0 or higher, and html5lib 1.1.
