MP500.db contains 100,315 ASE rows. XQueryer maps database entry ID n to class ID n - 1. MP500_xrd_database.pkl is the precomputed searchable database used by XMatcher.

Sources

When these assets support research, cite the related XQueryer paper and the XMatcher project as requested by the upstream authors.

Loading safety

MP500_xrd_database.pkl is a Python pickle. Loading an untrusted pickle can execute arbitrary code. Only load it from a trusted source after verifying the SHA-256 checksum above. MP500.db is a SQLite database and should likewise be treated as external input.

License

The XMatcher software source is MIT-licensed, but that software license does not by itself establish the redistribution license for the bundled MP500 data. The upstream data artifacts do not currently expose a single clear license in the available metadata, so this repository deliberately uses license: other. Users remain responsible for checking the original data terms and citations.
