Subgrouping of grammatical category

[gustafl]

Grammatical categories may be grouped into at least two subcategories along the following line:

• Categories that describe the lexeme (e.g. gender, or abstract/concrete nouns).
• Categories that describe inflected forms (e.g. gender and number).

This subgrouping is necessary to deal with the separation of lexemes and inflections in the application. While the user fills in the properties of the lexeme, the properties that only describe inflected forms should remain hidden or disabled, and vice versa.

Note the overlap with gender, which belongs in both subcategories. This is the only case I know of, but there are probably others.

We need a new column for this distinction in the grammatical_category table. Decide on a name and data type for the new column.

I've decided upon the name subgroup and the data type BIT(2). The complete list of values for the column are:

00 = Undefined 01 = Categories that describe the lexeme only 10 = Categories that describe the inflection only 11 = Categories that describe both

Done.
