The Gellish Expression Format

The Gellish Expression Format is a tabular format. It can be expressed in various basic formats, such as CSV, JSON or spreadsheet formats, such as XLS, typically using the UTF-8 encoding standard. The following columns in the table form the core of the expressions, using English terminology and provided with an example of a Gellish expression:

31 101 3 201 7
Name of an intentionName of a left hand objectName of a kind of relationName of a right hand objectSymbol of unit of measure
assertionThe Euromastis located inRotterdam

The above Gellish expression table is language dependent and human readable. It can be made language independent by adding references to unique language independent identifiers (UIDs) by extending the table with columns for such UIDs as follows:

1 5 2 60 15 66
UID of an ideaUID of an intentionUID of a left hand objectUID of a kind of relationUID of a right hand objectUID of a unit of measure

Note that

  • the UIDs shall be distinguished from the numeric UIDs that are standard in Gellish. Users can make their own UIDs by a prefix followed by a colon (:), followed by free codes. In this example Column 1 with UID therefore contains the prefix 'pr' and code '101', resulting in UID pr:101.
  • The UID of an idea is intended for being used for making statements about the expression as a whole.
  • An 'assertion' is a standard kind of intention with the Gellish UID 970025.
  • The Euromast and Rotterdam do not appear in the Gellish Dictionary (assumed), thus the user can allocate his own UIDs for those concepts.
  • The kind of relation 'is located in' is a standard phrase for the standard kind of relation with UID 5138.
  • The unit of measure column is not applicable for this expression, thus the coloumns for the UID as well as the symbol is left empty. If the columns are not required in a whole table, then the columns can be deleted from the table.

Other columns are available for expression of contextual facts, such as status, date of creation, author, etc. Those columns can be added depending in the requirements of the user by selecting them from a list of available columns. The columns may be arranged in any order that is convenient for the user. Multiple tables can be combined and different tables may consist of different collections of columns. A detailed specification of the definition of the tabular format is given in the document 'The Gellish Syntax and contextual facts' that is available in the download section of the gellish website. Various examples of tables in Gellish Expression Format are given in the download area.
The table has three header columns. The first header row contains the following fields:

GellishEnglishVersionversion codedate of releasename or categoryfile name

The columns are identified by language independent column IDs in the second header row. The third header row contains free text names of the columns, corresponding with the column IDs.
