-A core concept of Gellish is the idea that any information that is expressed in Gellish forms a semantic network.

A semantic network is a network in which the nodes (concepts, things) are linked to each other by (binary) ​relations (relationships),​ whereas those relations have classification relations with other nodes that represent kinds of relations. Such networks can be about individual things as well as about kinds of things or both. 
-Furthermore,​ each such a semantic network is thus expressed in the formal language. This implies that by definition it forms an integrated whole with the semantic network that defines the formal language. In other word, the concepts that are used in expressions have explicit relations with concepts that are already defined in the language definition or are reused concepts that were defined earlier in the taxonomic dictionary. This means that any information that is expressed in Gellish forms an extension of virtually one integrated semantic network. Such an integrated network may also include expressions of knowledge and requirements as well as documents. Such an integrated network enables free navigation through a semantic network in any direction. For example from individual things to knowledge or requirements or definitions about kinds of things and vice versa. It also enables the specification of any sub-network of the total network as being a sub-model expressing some specific information.+Each such a semantic network is thus expressed in the formal language.

-An Integrated Information Model is a name for the scope of a semantic network that includes various kinds of information about some subject and always ​includes at least the language definition network. When such an information model concerns a facility, a product, a building, etc., then the result can be called a **Facility Information Model**, a **Product Information Model**, a **Building Information Model (BIM)**, etc.+Integrated information in Gellish is information that is expressed as a semantic network and that forms an integrated whole with the semantic network that defines the family of Gellish languages and that obeys the rules of Gellish so that it is automatically also integrated with other information (any other semantic network) that is also expressed in Gellish.  
 +An Integrated Information Model is a name for the scope of a semantic network that includes various kinds of information about some particular ​subject and that is always ​integrated with least the language definition network. When such an information model concerns a facility, a product, a building, etc., then the result can be called a **Facility Information Model**, a **Product Information Model**, a **Building Information Model (BIM)**, etc.
  
-The Gellish Modeling Methodology aims to increase the quality and accessibility of information (documents and data) about one or more subjects (such as a facility ​or a collection of products) and at the same time to reduce costs of managing data about the subjects and prossibly ​about their use. The basic vehicle for that is the development and use of electronic ''​Integrated Information ​Models.''​ Such a model typically ​is a model of one or more individual things ​that can be either ​designs of particular ​objects ​or may be about real world objects ​or kinds of things, or both. For example, it can be a design of a complete process plant, a building, a road or a road network, a ship or an airplane (which designs are imaginary individual things that only exist in peoples minds), and it can be an object that is fabricated, constructed and installed, operated and maintained or about components of such things ​or about kinds of things. It can also be about any combination of them.+The Gellish Modeling Methodology aims to increase the quality and accessibility of information (documents and data) about one or more subjects (such as facilities ​or a collection of products ​and/or processes) and at the same time to reduce costs of managing data about the subjects and possibly ​about their use.

It defines the '​common language'​ of the Information Models.
