0.9.87 A resource is an individually identifiable asset such as a video or audio clip, an image, or a textual asset. A resource may also potentially be a physical object. All resources must be locatable via an unambiguous address. Specifies the encoding format used to include the resource by value in the DIDL XML document. A list of ID values defined in SELECT_ID attributes of SELECTION elements, indicating the set of default selections for this choice. A condition describes the enclosing element as being optional, and links it to the selection(s) that affect its inclusion. Multiple predicates within a condition are combined as a conjunction (an AND relationship). Any predicate can be negated within a condition. Multiple conditions associated with a given element are combined as a disjunction (an OR relationship) when determining whether to include the element. Identifies elements that are annotated Specifies the data type of the resource, before any of the content-encodings specified in the CONTENTENCODING attribute were applied to the resource, as a concatenation of MIME media-type, sub-type, and parameters, as defined in IETF RFC 2045. A fragment unambiguously designates a specific point or range within a resource. Fragment may be resource type specific. Serves as the target for an ASSERTION element. This generalises over a couple of different things, all included in the URI _syntax_ definition. A statement is a literal textual value that contains information, but not an asset. Examples of likely statements include descriptive, control, revision tracking or identifying information. The DIDLINFO element allows information applicable only to the DIDL document to be included in the DIDL document. A container is a structure that allows items and/or containers to be grouped. A URI of the DIDL document. A string specifying a fragment identifier as defined in IETF RFC 3986 that locates the part of interest within the associated resource. Basically some metadata about the controlling schema for the aggregation in stance A selection describes a specific decision that will affect one or more conditions somewhere within an item. If the selection is chosen, its predicate becomes true; if it is not chosen, its predicate becomes false; if it is left unresolved, its predicate is undecided A choice describes a set of related selections that can affect the configuration of an item. The selections within a choice are either exclusive (choose exactly one) or inclusive (choose any number, including all or none). The DECLARATIONS element is used to define a set of DIDL elements - without instantiating them - for later use in a document via an internal reference. An item is a grouping of sub-items and/or components that are bound to relevant descriptors. An ID value that can be referenced in a CONDITION element. A component is the binding of a resource to all of its relevant descriptors. Minimum number of selections that are required to be made. If not present, there is no minimum number. An element that declares a particular state of the aggregation during processing to be true or false. An assertion defines a full or partially configured state of a choice by asserting true, false or undecided values for some number of predicates associated with the selections for that choice. An anchor binds descriptors to a fragment, which corresponds to a specific location or range within a resource. This entity models the top node of the datamodel, not the document it may be contained in. An unsigned integer value indicating the relative ranking of this ANCHOR among the other anchors in an ITEM. The ANCHOR with the highest precedence value is the default anchor for the ITEM. If this attribute is omitted, the precedence of the anchor is zero Elements that express a rank order of their associated object over other, similar objects Identifies the elements being annotated Maximum number of selections that are allowed to be made. If not present, there is no maximum number. A descriptor associates information with the enclosing element. This information may be a component (such as a thumbnail of an image, or a text component), or a textual statement. an IDREF to the file element which corresponds with the div containing this ftpr. an optional XML ID value A container for collections of behaviours and relations between them. 0.2.5
