By seperating the concepts of Feeds and FeedInstances, it is possible to store multiple feeds in a model, and keep temporally varying instances seperate. It is possible to attach additional properties to the FeedInstance to describe its origin, such as the date that the feed was polled. Entry Entry (identified by a URI) EntryInstance An instance of an Entry appearing in an Atom document. By seperating the concepts of Entries and EntryInstances, it is possible to store multiple entries in a model, and keep temporally varying instances seperate. It is possible to attach additional properties to the EntryInstance to describe its origin, such as the date that the feed was polled. Person Person Construct. Person constructs don't require PersonInstances, as Person's are not identified by URIs Generator Describes software used to create a feed. Link Link Construct. Category Represents the properties of a category Extension Structured Extension Construct. Image A link to a logo or icon. PlainText Representing plain text content HtmlText A subclass of Text for representing HTML content XhtmlText A subclass of Text for representing XHTML content ExternalContent Representing external content BinaryContent A class representing base64 encoded binary content with a MIME type XmlContent A class representing XML content with a MIME type TextContent Representing text content with a MIME type linkRel Link relation type. linkType Link MIME media type. linkHref Link target URI. linkHrefLang Link resource language. linkTitle Link title. linkLength Link resource size (in bytes). category Category of feed or entry. contentBase Base URI of XML Literal in rdf:value sibling. Used by Text constructs, content, and structured extensions. contentLang Base xml:lang for XML Literal in rdf:value sibling. Used by Text constructs, content, and structured extensions. contentSource URI of external content. mimeType MIME content type of a content element. extension An embedded Structured Extension construct. This property can be used to preserve unknown Structured Extensions so that they can be round-tripped between Atom Syntax and Atom/RDF. When the semantics of a Structured Extension construct are known, it may be appropriate to use an Extension specific mapping instead. link A reference from a feed or entry to a web resource personUri A URI associated with a Person construct. personName The name of a Person. personEmail The email address of a Person. feed A relation from a concrete FeedInstance to a conceptual Feed. entryInstance A relation from a concrete EntryInstance to a conceptual Entry. containingFeed A relation from an EntryInstance to the Feed that it was packaged in. sourceFeed A relation from an EntryInstance to its source feed defined by its entry/source-feed element. If an entry has no entry/source-feed, then its origin feed is the same as its containingFeed. title The title of a feed or entry. author The author of the entry or feed. contributor A contributor to the feed or entry. updated The time of the last significant update to the entry or feed. published The time of creation or publication of the entry. summary A summary or abstract of the entry. rights A human readable intellectual property rights statement for the feed or entry. subtitle A human readable description or subtitle of the feed. generator Identifies the software used to create the feed. generatorName Identifies the name of the software used to create the feed. generatorUri Identifies a URI associated with the software used to create the feed. generatorVersion Identifies a version number of the software used to create the feed. content The content of the entry. icon An icon for the feed. logo A logo for the feed. imageUri The URI for the image - as a Resource categoryTerm The category term. categoryScheme A URI identifying the category scheme. categoryLabel A human readable label for the category term. extensionXML An XML Literal containing the extension including the element wrapper itself. extensionText The plain text value of an extension. If the extension contains mixed content, then this property will not be available. Provided for easier access to property values without requiring to parse the XML in triples. The atomrdf:extensionXML element should always be available, even when atomrdf:extensionText isn't. propertyNS The namespace URI of the root element of an extension. Provided for easier identification of the property type from the RDF model. The value is a literal to allow for support of the blank namespace. propertyName The localName of the root element of an extension. Provided for easier identification of the property type from the RDF model. base64Value The value of binary content as a base64 string. textValue The value of text or html text constructs, or text content. xmlValue The value of xhtml text constructs, or xml content.
