A 'wrapper' for all elements of the QuDEx Schema. The root element; a 'wrapper' for all other elements of the QuDEx Schema. Each top level element in QuDEx is defined as a ‘collection’. Child elements: resourceCollection, segmentCollection, codeCollection, memoCollection, categoryCollection, relationCollection. Attributes: @ id, @ "standard-attributes group", @ status. The resourceCollection section lists and locates all content available to the QuDEx file. A source points to the original location of the resource while each author working on the QuDEx file is assigned a surrogate document which points to the relevant source. The child elements sources and memoSources contain direct references to the files under analysis; the documents section contains their surrogates. Child elements: sources, documents, memoSources. Container class for holding the sources. Child element: source. Attributes: @id. Each source represents a single resource available to the QuDEx file. A source may be anything identifiable by a URI which is to be analysed using CAQDAS methodology. Each time a new @creator uses a source, a document surrogate is created. Other sections of the QuDEx instance reference the document rather than the source. Attributes: @id, @ "resource-attributes" group, @ "standard-attributes" group Container for holding the external memo sources. Child element: memoSource. Attributes: @id. In addition to creating a pure text memo and embedding it in the QuDEx file (inline memo) it is possible to reference an external memo using a memoSource. In QuDEx an external memo (held outside the body of the QuDEx file) is managed in the same way as an external source. A memoSource may be anything identifiable by a URI. Each time a new @creator uses a memoSource, a document surrogate is created. Other sections of the QuDEx instance reference the document rather than the source. Attributes: @id, @ "standard-attributes" group, @ "resource-attributes" group. The different sources included in the QuDEx file may be used by a number of authors. This container element permits this as a resource is designated a new ‘document’ for each author instance which uses the resource. Child element: document. Attributes: @id. A document is a surrogate version of a memo or memoSource specific to an individual author. The first time each author (@creator) uses a source or memoSource in QuDEx a surrogate document is created. This document is referenced by the various collection sections. The document concept permits the controlled re-use and analysis of each source and memoSource within a single QuDEx instance. A document may refer to any underlying resource (source or memoSource) that can be referenced by a URI including text, audio, video, still images and XML. Attributes: @id, @ "standard-attributes" group, @ documentType, @ resourceRef. The parent element for all segments. Child element: segment. Attribute: @ id. A subset of a document (text, audio, video or image) under analysis defined in a manner appropriate to the format (text, audio, video, image or xml). Segments may overlap and multiple memos and codes may be assigned to a segment Child elements: text, audio, video, image and xml. Attributes: @ id, @ "standard-attributes" group. Container for text document segment information. Child elements: lineParam, characterParam. Attributes: @ id @ src. Text document segment parameters based on lines and characters. Attributes: @id, @startLineOffset, @startOffset, @endLineOffset, @endOffset. Text document segment parameters based on characters. Attributes: @id, @startCharOffset, @endCharOffset. Container for audio segment information segments are defined. Child elements: param. Attributes are: @ id, @ src. audio segment parameters defined by start and end points for a clip. Clip annotation may be taken from the enumerated list or user-defined. Attributes : @id, @ clipBegin, @ clipEnd. Container for video segment information. Child elements: param. Attributes: @ id, @ src. video segment parameters defined by start and end points for a clip. Clip annotation may be taken from the enumerated list or user-defined. Attributes: @ id, @ clipType, @ otherClipType, @ clipBegin, @ clipEnd. Container for image segment information. Child elements: area. Attributes are : @ id, @ src Image segment parameters are defined by the shape and coordinates of an area within the image. Attributes: @ id, @ shape (expected values are: rectangle, circle or polygon), @ coords. Container for XML segment information. Child element: range. Attributes: @ id. XML segment parameters are defined by an Xpointer range Attributes: @ id, @ src, @ xPtrExp. The parent element for all codes. Child element: code. Attribute: @ id. A short alphanumeric string, usually a single word; may be assigned to a segment or document though assignment is not required. A code may optionally be taken from a controlled vocabulary defined under @ authority. Attributes: @id, @label, @cdate, @mdate, and @creator. The parent element for all memos; these may be pure text and embedded in the QuDEx file (inline memo) or may refer to external files. Child element: memo. Attribute: @ id. A text string internal to the document (inline memo) or an externally held document (external memo) which may be assigned to a segment, code, document, category or to another memo. Child elements: memoDocumentRef, memoText. Attributes: @ id, @ "standard-attributes" group. A reference to an external file to be used as a memo; the reference must be to a memoSource via the id of a document. Attributes: @ id, @ src. An inline memo held as a single variable length alphanumeric string. Attributes: @ id. The parent element for all categories. Child elements: category. Attributes: @ id. An alphanumeric string (stored in @label) assigned to one or more documents. Categories may be hierarchically nested. Documents contained within a category are referenced using @documentRefs. Nested categories are referenced using @categoryRefs. Attributes: @ id, @ documentRefs, @ categoryRefs, @ "standard group". The parent element for all relationships between objects. Child element: objectRelation. Attributes: @ id. A relation is a link between two objects in a QuDEx file. Each object is either the start or end point of a relation (source vs target). Every relation may, optionally, have a name. For the purposes of a relation all of the following are considered to be ‘objects’: a document (surrogate of a source or memoSource); a segment within a document; an assigned value (code, memo, category, relation). Attributes: @ id, @ objectType, @ relationName, @ otherRelationName, @ objectSource, @ objectTarget, @ "standard-attributes" group.
