Adding Elements to the Card Format

This section provides information about how to apply the elements available to create an

OpenCard card format. Elements are listed here in the order they are applied in the SVG card

format document.

Card Side Layers

Within the SVG document, a card format must define a front side layer and/or a back side layer.

• Use an ID of “CARD_FRONT” or “CARD_BACK”.

• Add personalization layers as children of each of the front and back side layers as needed.

• “CARD_FRONT” and “CARD_BACK” are the only layer IDs OpenCard recognizes at this level.

Re-Mapping Data Characters with datacard:translations

Translations allow for re-mapping of data characters. Using this element, the card format

designer can define a list of characters to translate.

The datacard:translations element is placed at the same level as the card side layers because

translations are applied to the data stream before it is merged into the card format. Translations

affect the value of the data merged into any operation defined in the card format.

Hexadecimal Notation for Translations

For datacard:translations, control characters with values of less than 0x20 (ASCII SPACE

character) must be encoded in hexadecimal notation using a leading 0x. For example, represent

the null character 0x00. If a translation maps any data stream character to a null (0x00) then the

presence of the null serves to end the data line at that point. Any data following the character

that translates to null is not merged into the card format.
