Metadata Profiles

This repository contains all Coscine Metadata Profiles (so-called application profiles).

Proposed Structure:

• ontologies Folder: contains subfolders with full schema definitions (properties + "word lists") of external definitions, no shapes
  • e.g. index.ttl for the definition of "external" properties like dcterms:title of Dublin Core metadata schema
• profiles Folder: Contains Metadata Profiles
  • e.g. radar/index.ttl with the Metadata profile.
• terms Folder: contains subfolders with full schema definitions (properties + "word lists"), no shapes
  • e.g. index.ttl for the definition of "internal" properties like current coscineode:simulation and its possible values
  • later for definition of fields we may need when converting current forms.
• vocabularies Folder: Contains "word lists" with a subfolder structure, no shapes
  • e.g. dc/dcmitype/index.ttl for the dublin core types. Try to stick to the usual naming conventions for the prefixes in Turtle.
  • e.g. dfg/dfgs/index.ttl for DFG Fachsystematik.
  • every vocabulary definition contains a coscine.ttl file which specifies the a coscinetype:Vocabulary relation and makes it available in Coscine (example: dc/dcmitype/coscine.ttl)

Stick to lower case letters for all folders.

Use purl.org/coscine/ as prefix.

File structure:

• Files containing Turtle syntax should have .ttl ending.
• Make sure .ttl are valid. E.g. define prefixes like rwth (unlike here)
• Make sure every file has a self descriptive "header" like

including a (dcterms:license and dcterms:publisher) or dcterms:rights statement. The example above has both for illustration purposes. If other information like creator are available include them or leave them in. Refere to https://spdx.org/licenses/ for license URLs.

• Make sure every vocabulary has a coscine.ttl file, if they are meant to be available in Coscine
