1//! The table set of one artifact.
2//!
3//! Every value is a byte string decoded by `record`, so a damaged artifact is
4//! a typed error at read time rather than a panic inside the database. Keys
5//! are dense ordinals; the vocabulary tables give each property key,
6//! designation use, and language reference set its ordinal and name.
