Adjusting Metadata Requirements
Document Entry Metadata
The following table lists each Document Entry metadata element, the optionality specified in TF Vol. 3 as used by XDS and the suggested minimal optionality.
| Metadata Attribute | XDS | Minimal | Discussion |
|---|---|---|---|
| author | R2 | R2 | |
| classCode | R | R2 | |
| confidentialityCode | R | R2 | |
| creationTime | R | R2 | |
| entryUUID | R | R | |

Documenting Metadata
As part of this project we should consider adjusting the way that metadata is presented in volume 2. A suggestion is to create a simple table without any explanation with columns:
- Attribute Name - just lists the common name of the attribute
- Data Type - identifies the type of content the attribute contains
- References - links to places where this attribute is discussed
- Requirements: - lists the required level of the attribiute in several different contexts
- Provide & Register (XDS)
- Provide & Register (XDR)
- Register
- Query Request
- Query Response
- Distribute Document Set on Media
Alternatively, the above table could be greatly simplified by having a section for each attribute that explains much of the above in appropriate details. So a section might look like:
4.1.7.n <Attribute Name>
Desciption:
Coding:
- Coding in Provide & Register and Register Transactions
- Coding in Query Request
- Coding in Query Response
Required Use:
- Requirements in use in XDS
- Requirements in use in XCA
- Requirements in use in XDR
- Requirements in use in XDM

Here is a list of projects around the world that make use of XDR and/or XDM
- U.S. Direct Project - XDR and XDM for Direct Messaging
- Australia - SMD/XDR/XDS harmonization
