3.1 Definitions
For the purposes of this document, the following terms and definitions apply. The IEEE Standards Dietionari’ Online should be consulted for terms not defined in this clause.
aggregate element: A LOM data element that contains other LOM data elements called subelements. See also: suhelement.
coniponent F.xtensihle Markup Language Schema definition (component XSD): An Extensible Markup Language Schema definition that defines a constituent of a composite schema. See also: composite Extensible Markup Language Schema definition.
composite Extensible Markup language Schema definition (composite XSD): An Extensible Markup Language Schema detinition that is a structure made up of distinct component XML Schema definitions. See also: component Extensible Markup Language Schema definition,
content model: A framework that identifies the makeup (i.e., data types. multiplicity constraints, ordering) of a spccitic model.
data type: A property of distinct values that indicates the common features of those values and operations on those values.
extended data element: A data element that is not defined in the LOMvI.O base schema. See also:
LOMvI.O base schema.
extended vocabulary: A value space that is not defined in the LOMvl.0 base schema for a LOM data element of type Vocabulary. See also: LOMs’l.O base schema.
Extensible Markup Language Information Set (XML Infoset): An abstract data set that provides a consistent set of definitions for use in other specifications that need to refer to the information in a well- formed XML document(W3C. XMl. Information Set). See also: post-schema-validation infoset.
Extensible Markup Language Schema binding (XML Schema binding): A textual representation of the behaviors, attributes, and value space of a data model element in W3C’ XML Schema definition language.
learning object: Any entity. digital or nondigital. that may be used for learning. education, or training.
(IEEE Std 1484.12.1-2002)
learning object metadata data element (l.ONI data element): A data element for which the name, explanation, size, ordering, value space, and data type are defined in IEEE Std 1484.12.1-2002. See also:
LOMs’l.O base schema.
learning object metadata Extensible Markup Language instance (tOM XML instance): A collection of metadata for a learning object that conforms to IEEE Std 1484.12.1-2002, that is represented in XML, and that adheres to the requirements and constraints of the XML Schema binding.
LONIvl.O base schema: A structured collection of standard data items. including their data types. multiplicities. and containericomponent relationships, as defined in IEEE Std 1484.12.1-2002. Clause 6.
mixed content: An clement type has mtxed content when elements of that type may contain character data. optionally interspened with child eknaents. (W3C. Extensible Markup Language IXMLI 1.1)
%Iultipmrpoar luirrttet Iail Extensions type (MIMI: type): A raandard way of classifying content types on the Internet.
post-sehensa-salldatlon Immoset: A transfornsed x’ersasat of the XML infoset of a document ptuduccd by a conforming W3C XML Schema processor W3C XML Schema defines the data elements added to the XML infssiet of the original docunietst during validation to pioduec else post-schema-validation infoset. 5ev also. Extensible Markup Language infnrmatkwi set
subeletsie.t: A LOS! data element that is contatned within another LOSt data element called an aggregate element. A stthclcmeni may contain other suhelenients; in which case, it is aLso an aggregate element. See also: aggregate clement
totem: A character string. The saltat space ala token is the set of stings that do not contain the line feed (#xA) or tab (#x9) characlem, that have no leading or trailing spaces (#x20), and that have no internal sequences of two or more spaces. TIse lexical space is the set of strings that does not contain the line feed (#xA) nor tab (#x9) eharactets. that have no leading or trading spaces (#xZO). and that have no internal sequences of two or more spaces. The base type is nornializ.edString. Tokens are case sensitive. (Adapted (mm W3C. XMl. Schema Part 2). 5cr also: token set.
totem set: A set of tokens in which each token is unique. See also. token.
uniqueness constraint: A restriction placed on a LOS! data element that enforces that the LOM data element is iattque withtn a LOM XML tnstance. If a LOM data element has a sat iqueness constraint, tt appeats in a LOM XML instance zeto or one tune. Se-c also. learning object tnetadata data element.
value space: The set of values for a given data type, IISO.’IEC 11404:1996)
