[Building Sakai] Database UUID Storage

[Ryan VanDyke]

In looking through the Sakai database I'm noticing most of the fields that store universally unique identifiers (UUIDs) are set to 99 characters. For example "user_id" in table "sakai_user_id"map". As far as my research tells me and from examples of data I'm seeing already in the data base UUIDs don't exceed 36 characters in length (32 alphanumeric characters and four hyphens).

http://en.wikipedia.org/wiki/Universally_unique_identifier

Wondering if there is a reason for the oversized fields?

Regards,

Ryan Van Dyke
