Editing Modeling language (section)

=== Textual types ===
Information models can also be expressed in formalized natural languages, such as Gellish.<ref>* Andries van Renssen, [https://repository.tudelft.nl/islandora/object/uuid%3Ade26132b-6f03-41b9-b882-c74b7e34a07d Gellish, A Generic Extensible Ontological Language], Delft University of Technology, 2005.</ref> Gellish has natural language variants such as [[Gellish English|Gellish Formal English]] and Gellish Formal Dutch ([[:nl:Gellish Nederlands|Gellish Formeel Nederlands]]), etc. Gellish Formal English is an information representation language or semantic modeling language that is defined in the Gellish English Dictionary-Taxonomy, which has the form of a Taxonomy-Ontology (similarly for Dutch). Gellish Formal English is not only suitable to express knowledge, requirements and dictionaries, taxonomies and ontologies, but also information about individual things. All that information is expressed in one language and therefore it can all be integrated, independent of the question whether it is stored in central or distributed or in federated databases. Information models in Gellish Formal English consists of collections of Gellish Formal English expressions, that use natural language terms and formalized phrases. For example, a geographic information model might consist of a number of Gellish Formal English expressions, such as:

 - the Eiffel tower <is located in> Paris
 - Paris <is classified as a> city

whereas information requirements and knowledge can be expressed for example as follows:

 - tower <shall be located in a> geographical area
 - city <is a kind of> geographical area

Such Gellish Formal English expressions use names of concepts (such as "city") and phrases that represent relation types (such as {{angbr|is located in}} and {{angbr|is classified as a}}) that should be selected from the Gellish English Dictionary-Taxonomy (or of your own domain dictionary). The Gellish English Dictionary-Taxonomy enables the creation of semantically rich information models, because the dictionary contains more than 600 standard relation types and contains definitions of more than 40000 concepts. An information model in Gellish can express facts or make statements, queries and answers.
