Abstract

A method, system, and computer-readable code for retrieving style sheets from a directory or other repository, based upon partial characteristic matching. Characteristics are associated with style sheets, and retrieval is accomplished by specifying a pattern which includes one or more of the characteristics. Preferably, the style sheet characteristics are stored as LDAP (Lightweight Directory Access Protocol) objects in an LDAP directory. The style sheets may be encoded in Extensible Stylesheet Language (XSL), Document Style Semantics and Specification Language (DSSSL), or any other style sheet language having equivalent semantics.

a subprocess for creating an object, wherein said object comprises;

a first attribute, a second attribute, and a third attribute; and

wherein said subprocess for storing further comprises;

a subprocess for storing a unique identifier of said object in said first attribute;

a subprocess for storing said stored extracted characteristics in said second attribute, wherein said characteristic pairs are delimited from one another using a first special character and wherein said characteristic identifier is delimited from said characteristic value in each of said pairs using a second special character; and

a subprocess for storing a unique identifier of said object in said first attribute;

a subprocess for storing said extracted characteristics as an unordered set of values in said second attribute, wherein each of said values stores one of said pairs; and

a subprocess for storing said identifier of said selected style sheet in said third attribute.

7. Computer readable code for retrieving style sheets from a repository based upon partial characteristic mapping according to claim 6, wherein said characteristic identifier and said characteristic value in each of said pairs are delimited using a special character.

8. Computer readable code for retrieving style sheets from a repository based upon partial characteristic mapping according to claim 5 or claim 6, wherein said repository is a directory database.

9. Computer readable code for retrieving style sheets from a repository based upon partial characteristic mapping according to claim 8, wherein said directory database is an LDAP database, and said object is an LDAP object.

10. A system for retrieving style sheets from a repository based upon partial characteristic mapping in a computing environment capable of having a connection to a network, comprising:

means for associating one or more characteristics with each of one or more style sheets;

means for extracting each of said associated characteristics for selected ones of said style sheets; and

means for storing said extracted characteristics for each of said selected style sheets in said repository, along with an identifier of said selected style sheet to which said stored characteristics pertain.

11. The system for retrieving style sheets from a repository based upon partial characteristic mapping according to claim 10, further comprising:

means for specifying a pattern for a desired set of characteristics;

means for matching said pattern against a collection of said stored characteristics from said repository; and

means for retrieving a particular style sheet using said style sheet identifier located by said means for matching when said means for matching has a successful result.

12. The system for retrieving style sheets from a repository based upon partial characteristic mapping according to claim 11, wherein said associated characteristics are specified as pairs, each of said pairs comprising a characteristic identifier and a characteristic value for said identifier.

13. The system for retrieving style sheets from a repository based upon partial characteristic mapping according to claim 12, wherein said pattern comprises one or more sub-patterns, each of said sub-patterns comprising a specified characteristic identifier and a specified characteristic value, wherein said specified characteristic identifier and said specified characteristic value may use one or more wildcard characters.

14. The system for retrieving style sheets from a repository based upon partial characteristic mapping according to claim 12, further comprising:
