augment metadata with soil property/threat/function

[pvgenuchten]

Metadata records are tagged using keywords, preferably these keywords originate from controlled vocabs (thesauri). SWR uses these keyword+vocab combi's (subjects) to filter and aggregate

First we need to identify which controlled vocabs should be used, the landmark and ejpsoil project have made suggestions for vocabs to be used, the soil-health-knowledge graph (developed by beichen) can also accomodate these lists. Potential candidates

• Glosis ontology
• Agrovoc
• Gemet
• INSPIRE registry

Options:

• analyse keywords, if a keyword matches a keyword from vocab, augment the keyword to be based on vocab, a translation from source to english could be relevant
• use same-as type of relations to resolve existing vocab+keyword combinations to theire representatives in the selected vocabs
• derive from content relevant keywords using nlp/llm

By increasing the number of records having these tags, we can improve visualisations such as below:

I will leave this to Beichen for now, please tag me again if needed.
