@hypercerts-org/lexicon 1.4.0

This release adds first-class records for non-agent subjects, together with shared tags for describing features and collections.

Represent non-agent subjects

The new org.hypercerts.entity.feature record represents a subject that is not a person or organization. Examples include a managed land zone, ecological stratum, participant cohort, or campaign.

A feature can include:

• a title, description, and general type
• tags describing the feature
• optional location records when the subject is spatial
• external identifiers through sameAs

Collections can now include features alongside activities and nested collections. Existing activity claims continue to reference app.certified.location directly and do not need to change.

Add shared tags to features and collections

The new org.hypercerts.vocab.tag record lets publishers define tags that features and collections can share.

For example, a land feature could have both a "project site" tag and a "mangrove land cover" tag. Because each tag is published as a record, different features and collections can use the same definition instead of relying on inconsistent free-text values.

A tag can also record:

• alternative names
• a link to the equivalent term in another standard
• whether it has been retired and replaced
• the more general tags it belongs under

When a feature or collection has several tags, they are all treated as facts about that record. Tags do not express OR, NOT, weighting, or other logic.

Compatibility

These changes are additive. Existing records remain valid.

Thanks @DjimoSerodio for contributing these changes in #242.
