Minutes¶

XML rendering updates and advancements to the flat schema¶

• Discussed whether to have a single schema with both flat or hierarchical or two schemas (one for each). Having one schema is much better for interoperability. Agreement that solely flat or both flat and nested is preferred, and that we would not want a solely nested schema.

• Discussed a standard and interoperable flat schema, plus an informational document (not a standard) showing examples of how some infrastructures have constructed a hierarchical rendering. Infrastructures that for internal reasons want hierarchical would publish flat for interoperability, and also hierarchical for internal use. Noted that anyone could write a tool to convert flat to hierarchical and share it with the community.

Progress on LDAP rendering document with respect to DIT standardisation¶

LDAP queries can handle any hierarchy and don't change when the hierarchy changes.
Need to change STRING definition from ASCII to UTF-8. This could be considered a bug in the original rendering specification.

We agreed that UTF-8 should be specified in the Schema and applied to all renderings.

Unified GLUE enumerations and process to update them autonomously¶

Florido is continuing to collect enumerations and put them in a Google doc.
Publishing in a machine readable as a GIT file should satisfy the needs.
Florido will put enumeration in GIT in different formats (XML, JSON, CSV, etc...) by middle of November
