Changes for the ZeeRex DTD, version 2.0
26th January 2004
Changes between versions
1.9
and
2.0
Backwards incompatible changes are highlighted in
red.
- Added transport attribute to serverInfo.
- Renamed indexSet element to
set.
- Renamed indexSet attribute to
set.
- Renamed attributeSet attribute to
set.
- Renamed uri attributes to
identifier.
- Renamed oid attributes to
identifier.
- Removed name element from schema,
replaced as an attribute.
- Added implementation element to databaseInfo.
- Removed required order of elements in configInfo.
- Modified semantics of name element in maps.
- Added lists of links and configInfo types to documentation.
- Updated list of protocol types in documentation.
The general thrust of all these changes is to make ZeeRex more
suitable for its central role in the new version 1.1 of
the SRW protocol,
including harmonisation of the representation of equivalent concepts
in SRW and Z39.50. For example, the old
SRW-specific element
<indexSet>
and the
Z39.50-specific element
<attributeSet>
are harmonised into a single
<set>
element.
