A: SeMRA is released under the permissive MIT License. ## Why It Matters Semantic mapping and reasoning are central to integrating heterogeneous biomedical data, enabling automated inference, and supporting reproducible research workflows. SeMRA delivers these capabilities as a lightweight, Python‑native library, lowering the barrier for developers and scientists to embed semantic operations directly into their pipelines. By being part of the Biopragmatics Stack, it interoperates with a suite of related tools, fostering a cohesive ecosystem for bio‑ontological engineering. Its open‑source MIT licensing encourages community contributions, rapid iteration, and broad adoption across academic and industry projects. The steady release cadence—from version 0.0.2 in 2023 to 0.1.3 in 2025—demonstrates active maintenance and responsiveness to user needs, ensuring that the package stays current with evolving standards and dependencies in the Python data‑science landscape. ## Notable For - **First‑class integration** into the Biopragmatics Stack, positioning it as a core component for semantic bio‑informatics workflows. - **Rapid, continuous releases** (nine stable versions between 2023‑2025), reflecting active development and community support. - **Broad dependency set** that bridges general‑purpose data handling (Pandas, tqdm) with specialized ontology tools (Bioontologies, PyOBO). - **MIT License** offering maximal freedom for commercial and academic reuse. - **Dual classification** as both a “Python package” and generic “software” on Wikidata, enhancing discoverability across repositories. ## Body ### Overview Semantic Mapping Reasoning and Assembler (SeMRA) is a Python package designed to facilitate semantic mapping, logical reasoning, and assembly of ontology‑based data structures. It is classified under the Wikidata description “Python software package” and is part of the larger Biopragmatics Stack, a collection of tools for pragmatic bio‑ontological work. ### Development History - **Initial release (0.0.2):** 15 August 2023, marked as a stable version. - **Subsequent stable releases:** 0.0.4 (25 Oct 2023), 0.0.5 (27 Nov 2023), 0.0.7 (6 Feb 2024), 0.0.8 (11 Apr 2024), 0.0.9 (17 Apr 2024), 0.1.0 (30 Apr 2025), 0.1.1 (6 May 2025), 0.1.2 (24 May 2025), and 0.1.3 (17 Jul 2025). Each release is documented on GitHub with a dedicated tag and release note. ### Licensing & Distribution - **License:** MIT License, as listed on the PyPI project page. - **Distribution channels:** - **PyPI:** Project name `semra`. - **GitHub:** Source code repository at `https://github.com/biopragmatics/semra`. - **Issue tracker:** `https://github.com/biopragmatics/semra/issues`. ### Technical Stack - **Programming language:** Python. - **Core dependencies:** - **PyStow** – configuration and storage handling. - **Pandas** – data manipulation. - **pydantic** – data validation and settings management. - **tqdm** – progress bar utilities. - **more‑itertools** – extended iterator tools. - **NetworkX** – graph‑theoretic operations. - **Bioontologies** & **PyOBO** – ontology access and manipulation. - **typing‑extensions** – advanced type hints. ### Integration Within Biopragmatics SeMRA’s role in the Biopragmatics Stack is to provide a reusable, programmatic interface for constructing and reasoning over semantic maps. Its design aligns with other stack components, enabling seamless data flow from ontology ingestion (via PyOBO) through graph construction (NetworkX) to downstream analytics (Pandas). ### Community & Maintenance The project is maintained by its creator, Charles Tapley Hoyt, and welcomes contributions via GitHub.
