Schema Document Properties

Target Namespace http://www.tdwg.org/2003/SDD_09
Version SDD 0.9.030
Element and Attribute Namespaces
  • Global element and attribute declarations belong to this schema's target namespace.
  • By default, local element declarations belong to this schema's target namespace.
  • By default, local attribute declarations have no namespace.
Documentation

Contains only infrastructure: GenerationMetadata, ProjectDefinition, Resources! This version has been created only for the purpose of focussing the discussion of the SDD working group. It is NOT a functional schema!



Should audiences become a root section? Would a predefined set of audiences be included in multiple projects?

ResourceConnectors and references to these objects:

Metadata (application, revision, IPR; Creators and RevisionData are closely related to the AgentRefsType defined above):

Annotations of objects occur together with labels or similar identifying objects. However, are not audience-specific and separate from the Label collection:

Key/ref infrastructure:

Basic simple types:

Global Declarations

Element: Document

Name Document
Type Locally-defined complex type
Nillable no
Abstract no
Documentation Provides root element. Note that the version of the SDD standard used is defined in the namespace declaration and needs no separate data element. Note: until xInclude is sufficiently widespread implemented to combine data from different documents, terminology, descriptions, and resources must be in the same document!

Complex Type: ApplicationDataType

Super-types: None
Sub-types: None
Name ApplicationDataType
Documentation Application specific data, providing an extension mechanism to the SDD model. SDD conforming editing applications are expected to preserve the information of other applications when importing and later exporting data to support lossless round tripping. Recommendation: Each application may read out its own information. Any other target information present should be preserved and output when a new document is generated. This is designed to support item potent round tripping data between two applications. This implies that no dependency between the settings and the descriptions and the terminology setting should be relied upon.

Documentation Describes the application or script that produced this document (whether it has been authored there or not).

Intended for debugging purposes and to improve import quality (esp. if some generators are known to produce problematic code). Furthermore, attributes describe whether the data contained in the document are complete or an excerpt of a larger data set.

Glossary

Abstract (Applies to complex type definitions and element declarations). An abstract element or complex type cannot used to validate an element instance. If there is a reference to an abstract element, only element declarations that can substitute the abstract element can be used to validate the instance. For references to abstract type definitions, only derived types can be used.

All Model Group Child elements can be provided in any order in instances. See: http://www.w3.org/TR/xmlschema-1/#element-all.

Choice Model Group Only one from the list of child elements and model groups can be provided in instances. See: http://www.w3.org/TR/xmlschema-1/#element-choice.

Collapse Whitespace Policy Replace tab, line feed, and carriage return characters with space character (Unicode character 32). Then, collapse contiguous sequences of space characters into single space character, and remove leading and trailing space characters.

Key Constraint Like Uniqueness Constraint, but additionally requires that the specified value(s) must be provided. See: http://www.w3.org/TR/xmlschema-1/#cIdentity-constraint_Definitions.

Key Reference Constraint Ensures that the specified value(s) must match value(s) from a Key Constraint or Uniqueness Constraint. See: http://www.w3.org/TR/xmlschema-1/#cIdentity-constraint_Definitions.

Model Group Groups together element content, specifying the order in which the element content can occur and the number of times the group of element content may be repeated. See: http://www.w3.org/TR/xmlschema-1/#Model_Groups.

Nillable (Applies to element declarations). If an element declaration is nillable, instances can use the xsi:nil attribute. The xsi:nil attribute is the boolean attribute, nil, from the http://www.w3.org/2001/XMLSchema-instance namespace. If an element instance has an xsi:nil attribute set to true, it can be left empty, even though its element declaration may have required content.

Preserve Whitespace Policy Preserve whitespaces exactly as they appear in instances.

Prohibited Derivations (Applies to type definitions). Derivation methods that cannot be used to create sub-types from a given type definition.

Replace Whitespace Policy Replace tab, line feed, and carriage return characters with space character (Unicode character 32).

Sequence Model Group Child elements and model groups must be provided in the specified order in instances. See: http://www.w3.org/TR/xmlschema-1/#element-sequence.

Substitution Group Elements that are members of a substitution group can be used wherever the head element of the substitution group is referenced.

Substitution Group Exclusions (Applies to element declarations). Prohibits element declarations from nominating themselves as being able to substitute a given element declaration, if they have types that are derived from the original element's type using the specified derivation methods.

Target Namespace The target namespace identifies the namespace that components in this schema belongs to. If no target namespace is provided, then the schema components do not belong to any namespace.

Uniqueness Constraint Ensures uniqueness of an element/attribute value, or a combination of values, within a specified scope. See: http://www.w3.org/TR/xmlschema-1/#cIdentity-constraint_Definitions.
