The diagram below depicts the core classes of the LDT vocabulary. (Show original size)

Classes

Appearance

The appearance for a particular representation. You should only use the predefined appearances of the Linked Data Theatre:

• TableAppearance;
• ShortTableAppearance;
• ContentAppearance;
• HeaderAppearance;
• NavbarAppearance;
• NavbarSearchAppearance;
• HiddenAppearance;
• LoginAppearance;
• CarouselAppearance;
• IndexAppearance;
• TreeAppearance;
• HtmlAppearance;
• GraphAppearance;
• TextAppearance;
• FormAppearance;
• GeoAppearance;
• GeoSelectAppearance;
• ImageAppearance;
• ChartAppearance.

Constraint

A constraint places on a fragment.

Container

A regular container. Updates to this container will be places in the graph with the same URI as the container.

VersionContainer

A versioned container. Updates to this container will be places in the graph with the URI of the container, concatenated with a hash ('#') and a timestamp. Updates will also be placed in the graph with the same URI as the container, including a dcterms:hasVersion statement.

Form

A form to be used when a mandatory URL parameter is not set.

Fragment

A part of a representation that defines how a fragment of a representation is presented.

Layer

The layer at which a representation is located. Three layers are defined:

• BottomLayer;
• DefaultLayer;
• TopLayer.

If no specific layer is defined, the DefaulLayer is used. Only representations located at the highest avaiable layer will be used.

Representation

The representation of some data

Style

The style of a fragment.

Translator

The translator used to translate non-RDF data into RDF data. Three translators are defined at this moment (these correspond with the filenames in the /translators folder).

• GenericExcelTranslator;
• SimpleExcelTranslator;
• SimpleTranslator;
• XMI21Translator.

Properties

url-pattern

The regex pattern to which a URL should conform for this representation. More than one url-pattern properties can be added. The URL should conform to at least one of the patterns.

applies-to

The applies-to property is used in three different ways:

• When used as a property of a Representation, it states the pattern that should match the resource description. For example: [rdf:type owl:Class] is a pattern that matches all resources of the type owl:Class.
• When used as a property of a Fragment, it defines the property or the variable for which the fragment is defined. For example: elmo:applies-to rdfs:label states that the frament is used for a rdfs:label property, and elmo;applies-to "graph" states that the fragement is used for the variable ?graph.

query

The property that defines the SPARQL query used for the representation.

data

Some static data.

contains

States that a representation contains some other representations. All containing representations will be presented below each other.

index

States the order in which fragments or representations are presented.

html

States that the object contains a string with html formatting. This property should be used with a HtmlAppearance.
