This invention relates to query management. A query management method includes receiving a database query, generating an abstract syntax tree representation of the database path query into a set of java objects, and processing the abstract syntax tree representation of the database path query. The method further includes determining a selector upon processing the abstract syntax tree representation of the database path query and deriving a SELECT clause from the selector clause, where the SELECT clause indicates a portion of an expression from an XMeta Query Language (XMQL) query. The method yet further includes appending a FROM clause to the expression for the XMQL query, appending a WHERE clause to the expression for the XMQL query, and executing the expression for the XMQL query including the appended FROM clause and also the appended WHERE clause to access objects in an object repository.

Accessing objects in a service registry and repository

This invention relates to a service registry and repository system, method and computer program product for accessing objects in an object repository. A method of managing an object database for objects comprising: receiving a database XPATH query; translating the database path query into an object query; and querying the object database using the object query. The translating comprises: breaking the path query into nodes; examining each node to identify objects for selection and objects from which selection is made; consolidating objects for selection from each node; consolidating objects from which selection is made; and forming the object query from a SELECT clause made up of the consolidated objects for selection from each node and from a FROM clause made up of the consolidated objects from which selection is made.

A hierarchical structure is provided. The hierarchical structure includes object items for objects located in the hierarchical structure, each object item having a name and a link. The hierarchical structure also includes node items each having a name of a hierarchical path name. A node item is provided for each unique path name in the hierarchical structure and the link of an object item links to a single node item having the hierarchical path name of the object.

Method and system for defining a heirarchical structure

Embodiments of the invention relate to a service registry and repository system, method and computer program product for accessing objects in an object repository. There is provided a method of managing an object database for objects that includes receiving an object query; querying the object database using the object query; receiving a hierarchical collection of objects including a root object; and returning only those objects that are within a specific depth of the root object and that do not represent user-defined relationships. The returning step maps the objects from a proprietary object format into a standard object format and optionally the standard object format is the Service Definition Object format (SDO).

Method for pruning objects in a service registry and repository

A service registry and repository method for managing an object database for objects. The method includes receiving a database path query expression including both a main expression and a treat-as expression. The method also includes translating the query expression into an object query and querying the object database using the object query. In particular, the translating includes breaking the expression into nodes, examining each node to identify objects for selection and from which selection is made, consolidating objects for selection from each node in the sub-expression into a sub-SELECT clause, consolidating objects for selection in each node of the main expression into a SELECT clause, consolidating objects from which selection is made from nodes in the sub-query into a sub-FROM clause, consolidating objects from which selection is made from nodes in the main query into a FORM clause, and forming the object query from the SELECT, FROM and WHERE clauses.

Accessing objects in a service registry and repository using a treat as function

A service registry and repository method, system, computer program product and web service for managing an object database for objects where each node for locating objects for selection utilizes predicates for the object; inferring subclasses of an identified class if a predicate is a class classification function; consolidating object predicates including subclasses if a predicate is a class classification function; and appending specific clauses to the object query, then querying the object database using the object query.

Accessing objects in a service registry and repository using subclass inference

This invention relates to a service registry and repository system, method and computer program product for accessing objects in an object repository. There is provided a method of managing an object database for objects comprising: receiving an object query; querying the object database using the object query; receiving a hierarchical collection of objects including a root object; and returning only those objects that are within a specific depth of the root object and that do not represent user-defined relationships. The returning step maps the objects from a proprietary object format into a standard object format and optionally the standard object format is the Service Definition Object format (SDO).
