Annotation

The class for Web Annotations.

• Class

annotationService

The object of the relationship is the end point of a service that conforms to the annotation-protocol, and it may be associated with any resource. The expectation of asserting the relationship is that the object is the preferred service for maintaining annotations about the subject resource, according to the publisher of the relationship. This relationship is intended to be used both within Linked Data descriptions and as the rel type of a Link, via HTTP Link Headers rfc5988 for binary resources and in HTML <link> elements. For more information about these, please see the Annotation Protocol specification annotation-protocol.

• Property

assessing

The motivation for when the user intends to provide an assessment about the Target resource.

• Motivation

bodyValue

The object of the predicate is a plain text string to be used as the content of the body of the Annotation. The value MUST be an xsd:string and that data type MUST NOT be expressed in the serialization. Note that language MUST NOT be associated with the value either as a language tag, as that is only available for rdf:langString .

• Property

bookmarking

The motivation for when the user intends to create a bookmark to the Target or part thereof.

• Motivation

cachedSource

A object of the relationship is a copy of the Source resource's representation, appropriate for the Annotation.

• Property

canonical

A object of the relationship is the canonical IRI that can always be used to deduplicate the Annotation, regardless of the current IRI used to access the representation.

• Property

Choice

A subClass of as:OrderedCollection that conveys to a consuming application that it should select one of the resources in the as:items list to use, rather than all of them. This is typically used to provide a choice of resources to render to the user, based on further supplied properties. If the consuming application cannot determine the user's preference, then it should use the first in the list.

• Class

classifying

commenting

• Motivation

CssSelector

A CssSelector describes a Segment of interest in a representation that conforms to the Document Object Model through the use of the CSS selector specification.

A resource which describes styles for resources participating in the Annotation using CSS.

• Class

DataPositionSelector

DataPositionSelector describes a range of data by recording the start and end positions of the selection in the stream.

• Class

PreferContainedDescriptions

An IRI to signal the client prefers to receive full descriptions of the Annotations from a container, not just their IRIs.

• Resource

PreferContainedIRIs

An IRI to signal that the client prefers to receive only the IRIs of the Annotations from a container, not their full descriptions.

• Resource

prefix

The object of the property is a snippet of content that occurs immediately before the content which is being selected by the Selector.

• Property

processingLanguage

The object of the property is the language that should be used for textual processing algorithms when dealing with the content of the resource, including hyphenation, line breaking, which font to use for rendering and so forth. The value must follow the recommendations of BCP47.

• Property

questioning

The motivation for when the user intends to ask a question about the Target.

• Motivation

RangeSelector

A Range Selector can be used to identify the beginning and the end of the selection by using other Selectors. The selection consists of everything from the beginning of the starting selector through to the beginning of the ending selector, but not including it.

• Class

refinedBy
