Consult the Oregon Digital to Hydra Collection Checklist spreadsheet in the linked data_working folder on Google drive to see the deadlines for submitting the mappings and linked terms.

Map metadata fields as Linked Data (YAML file)

a. Find fields and equivalent properties

  • View the fields for each collection in CONTENTdm (CDM) by accessing the administrative client (https://contentdm.oregondigital.org/cgi-bin/admin/), choosing the collection you want to view in the drop-down box, and clicking “Fields” in the upper right-hand toolbar.

  • Find corresponding terms in the Field Names columns to equivalent properties (not classes) in other metadata schemas. Dublin Core Metadata (http://dublincore.org/documents/dcmi-terms/) is the default for CDM and will suffice in there isn’t a more fitting property.

  • See the Metadata Resources document for links to sources for searching for schemas, properties, and controlled vocabularies.

b. Map fields in .yml file

  • Download and open the mapping.yml file template in the linked data_working folder on Google drive.

  • List the CISONICK of each field followed by a “:” (for example- ident: ). The CISONICKS can be found at the end of the URL of the field in CDM when you click “edit” to the right of the field name.

  • After the “:”, add the approved abbreviation for the schema that’s being used to map the field. Please refer to the Metadata Dictionary (https://docs.google.com/document/d/1pudn5bDMikQ0xlNv6cEnscDkakCyeRjPwVkFNNVp0JM/edit#heading=h.4xjto5aqul0) and/or the Metadata Standards spreadsheet in the linked data_working folder on Google drive for the correct spelling/format of the abbreviation. For example, you would now have identi: dct: (dct for Dublin Core).

  • After the mapping abbreviation, add the property you chose. Be sure to use the correct spelling and syntax that the ontology/vocabulary uses. It should now look like identi: dct: identifier (for http://dublincore.org/documents/dcmi-terms/#elements-identifier).

  • If any fields are skipped, list # SKIP in that field.

c. List the URLs of the schemas in the section above the collection mappings. List the abbreviation of the schema followed by a : with the URL in listed afterwards in “ “. For example, dct: "http://purl.org/dc/elements/1.1/"

Upload the file to the linked data_working folder on Google drive as month to map_mapping_abbreviation of collection. Example: June_mapping_oimb.yml.
