All fields used by all existing collections are defined in an XML Field Definitions file (see the current version here). A field may consist of multiple parts, and may be multivalued.
Alternately, though not strictly a "controlled" vocabulary, fields may be configured to remember the values entered into them and suggest those values when users begin typing terms.
Field Usage Guidelines
A subcommittee of the Image Collections Online Working Group is preparing recommendations for how the most popular shared fields are to be used and formatted. Those recommendations will be posted here when accepted by the Working GroupResulting from discussions with stakeholders and metadata experts, the Photocat Core Fields are now required as part of the setup of new collections in Photocat, the IUB Libraries' online image collection cataloging application. This field selection represents a unified endorsement of those elements widely shared by image collections. All new collections added to Photocat will automatically contain these fields and collections are encouraged to make use of them, adhering to the definitions for each field.
Collections imported from sets of images for which the image filenames contain useful descriptive metadata may be configured to display the original name of the file in this field. This value may not be edited, but is useful in searches or for uncataloged item identification.
Besides being used internally to track the status of a metadata record for an item, the status field is also tied to the public-facing web application to determine whether a particular field is public. Status values of "Minimal", "Pending Completion" and "Cataloged" will all be made available to the public (if the collection itself is published)fields are defined as:
- auto-generated: initial submission (you can't save a modified record with this status)
- in progress: indicates a record is being worked on and should not be published
- minimal: published, but has the minimal amount of metadata necessary
- pending completion: some checks may be necessary, not published
- cataloged: metadata is complete - published
We encourage you to use the status field as a guide for determining which records are complete and which need more work.
