This is part of a discussion around a geographic metadata model and an exchange protocol.
See also OSGeodataMetadataModel and generally OSGeodata.
Overview
A protocol specification consists of requests (operations) and responses (information model encoded in a streaming format and error messages, as codes).
We distinguish specifically query/search protocols and harvesting procotols.
Protocol Approaches: Searching or Harvesting?
Geographic Metadata Harvesting Protocol approaches and specifications:
- Use HTTP and XML ('autonomous discovery')
- OAI-PMH including a comparison with WFS (profiled)
Proposals
We tend to propose a harvesting approach which means, that
- in a first step OSGeodataMetadataModel encoded as XML files are published
- and in a second step OAI-PMH could be utilized (moving around the same XML files).
Better name sought (catalogue is probably not the most appropriate noun):
- Geographic Metadata Syndication Protocol
- Geographic Metadata Harvesting Protocol
- Other proposals?
- Geographic Data Discovery Protocol
- Geographic Metadata Dissemination Protocol
