Research Tagging and Categorization Vocabs for Bibliography documents
Currently each Bibliopgrahy item in DMX can haz one or many "dmx.tags.tag".
Research how others do it and decide if we want to stick with this.
- Identify assoc types that let us express hierarchies in between tags, e.g. like SKOS
- Scan solutions for other types of taxonomies then generic tags
- Such Bibliograhpy Tags would then appear across all other DMX applications (when using "dmx.tags.tag") but maybe users would understand them to be very something
- Alternatives: use "Concepts", e.g. from SKOS, or other
