Semantics templates

For the automatic validation of input values for symbolic semantics (strings), value templates must be assigned. Multiple templates can be assigned to one semantic characteristic; these templates are checked sequentially until a match with the semantic value is found.

A template can be defined either as: a set of allowed characters within square brackets, which matches a string of any length containing only those characters. Or as a string pattern of a fixed length, containing literal and special characters in specific positions.

The set of allowed characters can be specified, for example, as: [0123456789-+.e]. During the validation of the semantic value, the brackets themselves are ignored.

A string pattern with special characters can be defined like this: +7(999)999-99-99.

The following special characters are used:

A - only Latin letters (A…Z, a…z) are allowed in this position.

X - characters for a hexadecimal number (0…9, A…F, a…f).

9 - digits from 0 to 9.

Any other characters in the string pattern are checked for an exact match in the specified position.

Template Examples:

For a part of the template string enclosed in curly braces {}, the characters A, X, and 9 are checked as literal characters for an exact match, not as special characters. For example, with the pattern {X}, the semantic value must contain the literal character X.

A combined template can contain a fixed number of literal or special characters at the beginning of the string, followed by a variable number of characters from a specified set, and a fixed number of literal or special characters at the end of the string.

Examples of Combined Templates:

The user works with a selected template in the list. Editing is performed directly in the current row.

• To add a template, press the "+" button and type the required template in the new row.

• To delete a template, use the "-" button.

• To delete all templates in the list, press the "3" button.

• Use the "4" and "5" buttons to navigate through the list of templates.

• To copy a template to the clipboard, press the "6" button.

• To paste a template from the clipboard, press the "7" button.

To apply changes to the classifier, press the Save button.
