Status In implementation
Description The Fledged Data Service provides functionalities for a repository to expose/ disseminate its data to the world in a standardized way.
Operations Overview[edit]
OAI Compliance[edit]
The Fledged Data Service supports the Open Archives Initiatives Protocol for Metadata Harvesting (OAI-PMH).
The xslt for the transformation of a record needs to be placed in the presentation part of the service (src/main/resources), and the path needs to be specified in the fds.properties file.
The properties file can be found in the presentation module of the Fledged Data Service under: src/main/resources/fds.properties

Sitemap Creation[edit]
The sitemap functionality of the Fledged Data Service exploits the oai interface and creates a sitemap out of all items it retrieves with a ListIdentifiers call.
The interval of the sitemap creation can be configured in the fds properties file.
Example: RepositoryBaseURL/fledgeddata/sitemap.xml

[Planned feature] "Content negotiation is a mechanism defined in the HTTP specification that makes it possible to serve different versions of a document (or more generally, a resource representation) at the same URI ..." 1
