Controlled Vocabularies and Standards in Use

The following are the controlled vocabularies and standards that are in use by BDEARS. These are either system enforced (such as dates) or established through the use of defined vocabularies in the deposit workflow.

1. Dates: (all dc.date+qualifier fields) follow the ISO 8601 standard. This is generally enforced by the DSpace software in use.
2. Degree Name: The following terms are currently in use for degree name (thesis.degree.name): 

• B.A. (Bachelors of Arts), 
• B.S. (Bachelors of Science), 
• M.A. (Masters of Arts), 
• M.S. (Masters of Science), 
• Ph.D. (Doctoral)

1. Degree Level: The following terms are currently in use for degree level (thesis.degree.level):

• Dissertation
• Thesis

1. DOIs: Recently updated best practices from CrossRef and DataCite recommend displaying DOIs as full URLs. 

• All DOIs should be prefaced with 'https://doi.org/', not DOI:, doi:, dx.doi.org, or http://doi.org/
• CrossRef DOI example: https://doi.org/10.5468/ogs.2016.59.1.1
• DataCite DOI example: https://doi.org/10.7939/r3qz22k64

1. ISBN: ISBNs should follow the standard for 13 number ISBNs where possible.
2. ISSN: ISSNs should follow the standard for ISSNs.
3. Language: Language (dc.language) follows the ISO 639-2 standard, which uses three letter language codes.
4. MIME Type: BDEARS uses registered Media Types (or MIME Types) to display information about file formats. MIME Types are automatically added to any file in a format recognized by the DSpace software. See a complete list of MIME Type formats at Internet Assigned Numbers Authority https://www.iana.org/assignments/media-types/media-types.xhtml 
5. Type: BDEARS uses a subset of the Dublin Core DCMI Type vocabulary with some modification to names for the dc.type field. These are:

1. Identifiers: Each item that is deposited into BDEARS automatically receives a handle identifier, which can be thought of as the item's permanent home address/ url.

It is also possible to link to other versions of the item through Digital Object Identifiers (DOIs), Archival Resource Keys (ARKs), or other standardized uniform resource identifiers (URIs). It is preferable that the additional identifier be clickable; that is, it should direct a user to a web page.
