This page describes the interfaces for the imeji application. For data dissemination imeji exploits the Fledged Data Service of the eSciDoc SOA infrastructure.

RDF Export[edit]

RDF export interface for the imeji application.

Parameter: format, type, q, n

format: rdf, sitemap

type: Type of item (image, collection, album, mdprofile)

q: The query

n: The offset

Example: http://demo.imeji.org/imeji/export?format=rdf&type=image&n=10000&col=14

OAI Interface[edit]

imeji allows the fetching of metadata from its repository by supporting the Open Archives Initiatives Protocol for Metadata Harvesting (OAI-PMH).
The mapping of the native imeji rdf to oai_dc can be found here

Verb: Identify[edit]

Gives back information on the imeji Repository.
Parameter: None
Example: http://demo.imeji.org/fledgeddata/oai/?verb=Identify
Not supported: None

Verb: ListMetadataFormats[edit]

Gives back all metadata formats which are supported by the repository. All listed formats can be used as a parameter for a GetRecord request (currently collections and albums can only be fetched in native imeji format).
Parameter: None
Example: http://demo.imeji.org/fledgeddata/oai/?verb=ListMetadataFormats
Not supported: identifier

Verb: ListSets[edit]

Gives back a list of sets which are provided by the repository. imeji provides by default, all collections and albums as sets.
Parameter: None
Example:
Not supported: resumptionToken

Verb: GetRecord[edit]

Gives back a specific record, specified in the identifier parameter. A record can be everything with a url in imeji, currently: images, collections and albums.
Parameter: identifier, metadataPrefix
Example: http://demo.imeji.org/fledgeddata/oai/?verb=GetRecord&identifier=http://demo.imeji.org/item/gOjdOLDeEqXJbkvj&metadataPrefix=imeji
Not supported: Handling of deleted records

Verb: ListIdentifiers[edit]

Gives back the oai header for all images in the repository or, if set parameter is defined, all images of a set.
Parameter: metadataPrefix, set
Example: http://demo.imeji.org/fledgeddata/oai/?verb=ListIdentifiers
Not supported: from, until, resumptionToken

Verb: ListRecords[edit]

Gives back the metadata record of all images in the repository or, if set parameter is defined, all images of a set.
Parameter: metadataPrefix, set
Example: http://demo.imeji.org/fledgeddata/oai/?verb=ListRecords&metadataPrefix=imeji
Not supported: from, until, resumptionToken

http://upload.wikimedia.org/wikipedia/commons/a/a2/Farm-Fresh_sitemap.png Sitemap[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.
Therefore only image URLs will be listed in the sitemap.xml. The interval of the sitemap creation can be configured in the fds properties file.
Example:
