Jeff Faath commented on JUDDI-170:
----------------------------------
>From uddi spec:
"Keys in UDDI are declared as language independent case insensitive and must be
case-folded by nodes as part of processing any API. With the inclusion of the
attribute caseMapKind="fold" from Schema Centric Canonicalization in the schema
declaration for uddiKey type, the normalized form of a uddiKey element is
produced using Unicode Case Folding as defined in the Unicode Technical Report
on Case Mappings (see http://www.unicode.org/unicode/reports/tr21/)."

>
> In UDDI v3, the user supplies entity keys that become the primary key for the
> entity. The problem is, databases handle case sensitivity with queries. The
> code currently handles key comparisons with case insensitivity in mind,
> however, the "find" operation of the JPA EntityManager may react differently
> depending on the DB. In this case, if the user supplies a key that isn't the
> exact case of the entity they meant to work with, it will be treated as a new
> entity. Other unexpected behavior may occur as well.
> There are two ways to make this work for both case insensitive and case
> sensitive databases.
> 1) automatically convert all user-supplied keys to one case and store it that
> way (advantages: easy; disadvantages: doesn't preserve user case, for ex, if
> they want to use CamelCase for Ids)
> 2) No longer use the "find" operation and instead replace it with a case
> insensitive query (advantages: preserves user case; disadvantages: "find" is
> used quite a bit to test for existence, a SELECT query will need to be
> created for every entity that find was used)
