XSD Schema

The xsd schema is designed according to the following paradigm:

-- There are five xsd-types corresponding five sorts of resources in DASISH: CachedRepresentation, Source, User, Annotation, Notebook.

-- Each of these types has an obligatory attribute "URI" which contains DASISH identifier pointing to the location of the resource on the DASISH server.

-- There are five lists-of-reference types:CachedRepresentations, Sources, Users, Annotations, Notebooks. Their names are just plural English forms of the corresponding types.

-- There are corresponding resource-infor types: SourceInfo, UserInfo, AnnotationInfo, NotebookInfo. They contain reference to the corresponding resource plus the most important information about the resource. We have not introduced the info-type for Cached representations because there is no actual need for it and the type itself not that big.

-- There are corresponding list-of-resource-infor types: SourceInfos, UserInfos, AnnotationInfos,NotebookInfos.

There is a number of auxiliary types as well. A commonly-used one is ResourceREF which contains the attribute "ref" of type xs:anyURI. It allows to have announce elements-references and avoid mixing-them-up with elements-resources, without adding REF to the name. For instance <owner ref="http:/dasish.eu/users/UIDefef" />.

Responding GET api/annotations/AIDzyy (example usage for unresolvable target sources)

The respond for an annotation with unresolved target sources and the respond for an annotation with resolved target sources (see above) are both instances of the same schema element. However, the annotation refers to an obsolete version of the page. Later, having the target source references, the client will ask for the cached representations of the obsolete web-page.

Remarks by Menzo

For very dynamic and popular target sources the version list might become big, that could be a reason to move it to a separate call. Actually we have already GET api/sources/<sid>/versions, so I would leave them out here.

Olha's comment:

We have agreed earlier that the list of versions would include all the "siblings", include the source itself.Are there alternative ways to get all the siblings of a given source?

Request body for POST api/annotations

The version of the POST with an unknown target source, signalling the client to provide a cached representation for it:

TODO: Remove action request, instead note that we have to think about a solution, probably using an envelope with annotation result and set of action requests

TODO: Allow for temporary xml:id and xml:idref for referencing sources from body
