Support auto-import of attributes from more standard vocabularies and ontologies

[SamRepository]

Description:
It would be very useful if the generator could automatically pull and add attributes (metadata) from well-known vocabularies and
specialized ontologies.

Examples of well-known vocabularies include:

• FOAF (Friend of a Friend) → for persons and organizational agents
• GeoNames / GeO → for geographic and spacial entities
• SKOS → for taxonomies and organizations
  PROV-O → for provenance metadata

Examples of specialized ontologies include:

• PO (Plant Ontology)
• TO (Trait Ontology)
• ChEBI (Chemical Entities of Biological Interest)
• OBI (Ontology for Biomedical Investigations), etc.

Why this is valuable:

• Increases interoperability with established linked data standards
• Reduces redundancy by leveraging existing semantic structures
• Makes generated data more machine-actionable and integrable across domains

Potential Approach:

• Provide configuration options to enable/disable specific vocabularies
• Allow users to map generator-specific attributes to external ontology terms
• Auto-suggest commonly used properties (e.g., foaf:name, skos:prefLabel, prov:wasGeneratedBy)

This is a good suggestion, though will require some significant development. We will revisit this if we get time and money to develop this further.
