SDD Reduced xml schema version 1.0 (beta 2, incl. UBIF 1.0 beta 18)

This documentation is based on html code and graphics generated by the XML Spy schema editor (http://www.altova.com). It has been slightly modified by G. Hagedorn to make it more compact and readable. This is one of several available schema documentations; see the "Overview of available documentation" for further information.

element Datasets

diagram
properties	content  complex
annotation	documentation  Root element for files or data streams. Multiple Dataset objects are completely independent. Potential relationship may be detected by the consumer, but are not expressed in the UBIF format. The sequence of Dataset objects has no semantics and does not have to be preserved. The version of the UBIF standard used is defined in the namespace declaration and needs no separate data element.

element Datasets/Dataset

diagram
properties	isRef  0 content  complex
annotation	documentation  A single file or data stream may consist of multiple data sets

element Datasets/Dataset/Derivation

diagram
type	DerivationMetadata
properties	isRef  0 content  complex
attributes	Name Type Use Default Fixed Annotation datetime xs:dateTime required documentation  [ATTR: datetime] When did it occur? Date and time (UTC or local time with timezone information) at which the current document or data stream was created by the generator. Using UTC (Universal time coordinates = Greenwich mean time) is recommended.
annotation	documentation  ##This is a highly simplified version to concentrate discussion on SDD! Please look at UBIF itself for a discussion of this structure itself!

element Datasets/Dataset/ExternalDataInterface

diagram
type	ExternalDataInterface
properties	isRef  0 content  complex
annotation	documentation  Data from other knowledge domains to which the data set refers may be represented by collections of proxy data objects. In the absence of available external databases a proxy object may be used as a local placeholder. The data inside the proxy object usually provide a reduced interface data model that abstracts from a potentially more complex external data model. Examples: persons, publications, geographical localities, media resources, but also class names (biology: taxa) and objects/units (biology: specimens). ##To concentrate discussion on SDD some interface extensions are removed!

element Datasets/Dataset/Metadata

diagram
type	ContentMetadata
properties	isRef  0 content  complex
annotation	documentation  Metadata referring to the principal source of the entire data collection (the metadata scope may be wider than the objects actually contained in the data set). ##To concentrate discussion on SDD some parts are removed!

element DescriptiveData

diagram
type	DescriptiveData
properties	content  complex

complexType CategoricalCharacter

diagram
type	extension of AbstractCharacter
properties	base  AbstractCharacter

attributes	Name Type Use Default Fixed Annotation id CharacterRelationID required
annotation	documentation  # Derived from AbstractCharacter to be used in instance documents (non-abstract type). Categorical data include nominal and ordinal data (DELTA types UM/OM and NEXUS types). Other terms for categorical data in statistics are 'qualitative data' or 'attributes'. The term 'attribute' has been avoided in SDD because it has different definitions in statistics, programming, databases, DELTA, etc. Both 'qualitative' and 'attribute' are ambiguos as to whether ordinal/ ranked variables are in- or excluded.

element CategoricalCharacter/Assumptions/MeasurementScale

diagram
type	CategoricalMeasurementScaleEnum
properties	isRef  0 content  simple

element CategoricalCharacter/Assumptions/NaturallyContinuous

diagram
type	xs:boolean
properties	isRef  0 content  simple
annotation	documentation  Any categorical variable can assume only a limited number of discrete values. Thus data recorded in a CategoricalCharacter are always discrete (= discontinous or meristic). However, the measured property may either be naturally discrete ('male/ female', 'aseptate/ uniseptate/ biseptate/muriform'), or it may be continuously varying and partioned into into discrete categories ('no/few/many hairs', 'orange to red'). Only in the latter case the between-operator can be used on neighboring states.

annotation	documentation  Mappings between categorical states (e. g., subovate may be mapped to ovate to simplify identification choices).

element CategoricalCharacter/Mappings/Mapping

diagram
properties	isRef  0 content  complex
annotation	documentation  Each mapping defines a source and a destination state. Both From and To may point multiple times to the same state, but the combination From + To must be unique. Both state must be defined in the current character (validated through identity constraint!)

diagram
type	StateCollectionModelEnum
properties	isRef  0 content  simple default  OrSet
facets	enumeration  OrSet enumeration  OrSeq enumeration  AndSet enumeration  AndSeq enumeration  WithSeq enumeration  Between
annotation	documentation  Distinguishes different types of state collections. 'AndSet' and 'OrSet' define state distributions that are not explicitly ordered in instance documents. Applications may reorder states using the state order defined in Terminology or state frequency values/ranking. For the corresponding 'AndSeq'/'OrSeq' the sequences of states in instance documents defines the preferred order of states (distinguishing, e. g., between 'round or elliptic' and 'elliptic or round'). WithSeq expresses a specially worded form of 'AndSeq'. With 'Between' the scored states form a range around the true value ('orange' to 'red').

properties	base  VocabularyW1Base abstract  true
used by	complexTypes  CharacterConceptStateDef CharacterLocalStateDef
annotation	documentation  For categorical states. Used in concept (= 'project-wide') and local character state definitions. Any use of a character state in descriptions is a reference to an object of this type or one of its derivations.

element CharacterAbstractStateDef/UnconstrainedText

diagram
type	xs:boolean
properties	isRef  0 content  simple default  false
annotation	documentation  If present and true, the current state/ category allows unconstrained text not tied to a truly analytical state. Such states (which may be labeled: 'Text', 'Other:', 'none of the above, please specify:') prevent, especially if the terminology is still under development, that during data entry potentially inappropriate category must be chosen. DELTA text character are modeled using these states, but they also can occur in combination with categorical states. UnconstrainedText states are somewhat similar to the 'unknown' coding status, since the free-form text information is not available to most analytical processors (incl. identification programs). documentation  (This 2nd annotation contains detailed informations not entered in the first annotation, which is visible in the standard schema diagrams.) The name for this data element was contentious. Proposals were: Bob: IsIsolatedState with default false. Gregor: IsAnalyticalState, StateComparisonIsRecommended, or IsWellDefinedState, all with default true. ImpreciseEquality with default false? Furthermore, one may want to make a distinction between a category saying "enter free form text here" and one explicitly saying "none of the above". However, the action of choosing a separate free form text state instead of scoring a category (if available) and adding free-form note text, implies that choosing free-form text is always of the type "none of the above", whether this is explicitly stated in the text state label or not.

diagram
type	extension of DescriptionBase
properties	base  DescriptionBase
used by	element  DescriptiveData/CodedDescriptions/CodedDescription
attributes	Name Type Use Default Fixed Annotation id DescriptionRelationID required documentation  Defines a id for a coded or natural language description
annotation	documentation  Coded description data are highly controlled by the vocabulary and structures defined in the Terminology, using references to characters, states, modifiers, numerical values for measurements. They also support a limited amount of free-form text (in Notes or Annotation only). Separating data and terminology allows rearranging and refactoring the terminology, multilingual support through central terminology translations, and multiple hierarchical views. Coded descriptions must fulfill more rigorous consistency requirements than natural language descriptions and are more suitable for analysis. Furthermore, language-dependent annotations are minimized so that data can be easily reorganized and translated into multiple languages.
