Object Format List for DataONE

[taojing2002]

Format Metadata

Provide the standard metadata for the proposed format, ensuring that the id and name are unique and appropriate to the version of the format being proposed.

• formatId: http://ns.dataone.org/service/types/v1#ObjectFormatList
• formatName: Object Format List
• formatType: METADATA
• mediaType: text/xml
• extension:xml

Format description

When we install a new CN, we should insert the object which contains the list of object formats first before it functions. Currently we use the old Metacat API to insert/update it and the object is treated as a metadata object. However, after we disable the old Metacat API, we should use DataONE cn.create to insert the documents. If we don't have an object format identifier, which is a metadata type, for this object, CN will treat it as a data object.

Specification / Namespace documentation

The namespace is http://ns.dataone.org/service/types/v1

Provide the location(s) of the documentation of the format specification or the namespace for the format or vocabulary.

Checklist

• [x] The format is not a duplicate of another in the list under a different name or identifier
• [x] Format Identifier is unique
• [x] Format identifier is the commonly-used identifier for the namespace, or the best URI for the namespace, or the best Media type
• [ ] Format identifier is same as the MIME media type if the mime type is specific to only this format (e.g., image/png is specific to one format, whereas text/xml is not specific to one format)
• [x] Format Name is recognizable and sensible
• [x] Format includes version info where applicable in formatName and formatId
• [x] formatType is the correct type from the values: DATA, METADATA, or RESOURCE
• [x] MediaType is the most specific MIME media type that applies to the format

Considerations

Describe or list any considerations that might impact the use of the format, or related issues that we should consider.

@taojing2002 How about a fragmentID so the namespace resolves:

• formatId: http://ns.dataone.org/service/types/v1#ObjectFormatList

[mbjones]

I also updated the name to remove the DataONE, and switched to a hash symbol in the formatID.

[mbjones]

I also think the format should use DataONE V2 namespaces. So the final would be:

• formatId: http://ns.dataone.org/service/types/v2.0#ObjectFormatList
• formatName: Object Format List
• formatType: METADATA
• mediaType: text/xml
• extension: xml
