Abstract

A method, system and program product of managing multiple versions of enterprise meta-models within an enterprise model using semantic based indexing. The steps include: receiving a query; determining from the query a topic and at least two versions of a topic map meta-model of the enterprise meta-models to compare; applying the query to a merged topic map meta-model of the at least two versions of the topic map meta-model by searching a topic map based index of the merged topic map meta-model for the topic, producing a result; and using the result to translate the topic from the query in at least one of the at least two versions of the topic map meta-model to coexist and correspond to the other version of the topic map meta-model, allowing data between the at least two versions topic map meta-model of the enterprise meta-models within the enterprise model to be correlated.

Claims

1. A method of managing multiple versions of enterprise meta-models within an enterprise model using semantic based indexing, the method comprising the steps of:

a computer receiving a search query from a user;

the computer determining from the search query a topic and at least two versions of a topic map meta-model of the enterprise meta-models within the enterprise model to compare;

the computer applying the search query from the user to a merged topic map meta-model of the at least two versions of the topic map meta-model by searching a topic map based index of the merged topic map meta-model for the topic, producing a result; and

the computer using the produced result to translate the topic from the query in at least one of the at least two versions of the topic map meta-model of the enterprise meta-model to coexist and correspond to the other version of the topic map meta-model of the enterprise meta-model, allowing data between the at least two versions topic map meta-model of the enterprise meta-models within the enterprise model to be correlated.

2. The method of claim 1, further comprising:

the computer creating a version of a topic map meta-model including a topic map based index and instance ontology, for each version of the enterprise meta-model within the enterprise model, each version of the topic map meta-model being in a separate scope; and

the computer storing each version of the topic map meta-model in a repository.

3. The method of claim 1, further comprising:

the computer creating resource description framework triples for each version of the topic map meta-model; and

the computer storing the resource description framework triples into a repository.

4. The method of claim 1, further comprising:

the computer recursively creating a merged topic map in a scope, the merged topic map including a topic map based index and instance ontology for each additional version of the enterprise meta-model; and

the computer storing the merged topic map into a repository.

5. The method of claim 4, wherein the scope of the merged topic map is a scope newer than a scope of a previous version of the merged topic map.

6. The method of claim 1, wherein the search query comprises a domain and a scope.

7. The method of claim 6, wherein the search query further comprises a radix.

8. A computer program product comprising one or more computer-readable, tangible storage devices and computer-readable program instructions which are stored on the one or more storage devices and when executed by one or more processors, implement all the steps of claim 1.

9. A computer system comprising one or more processors, one or more computer-readable memories, one or more computer-readable, tangible storage devices and program instructions which are stored on the one or more storage devices for execution by the one or more processors via the one or more memories and when executed by the one or more processors implement all the steps of claim 1.

10. A computer program product for managing multiple versions of models using semantic based indexing, the computer program product comprising:

one or more computer-readable, tangible storage devices;

program instructions, stored on at least one of the one or more storage devices, to receive a search query from a user;

program instructions, stored on at least one of the one or more storage devices, to determine from the search query a topic and at least two versions of a topic map meta-model of the enterprise meta-models within the enterprise model to compare;

program instructions, stored on at least one of the one or more storage devices, to apply the search query from the user to a merged topic map meta-model of the at least two versions of the topic map meta-model by searching a topic map based index of the merged topic map meta-model for the topic, producing a result; and

program instructions, stored on at least one of the one or more storage devices, to use the produced result to translate the topic from the query in at least one of the at least two versions of the topic map meta-model of the enterprise meta-model to coexist and correspond to the other version of the topic map meta-model of the enterprise meta-model, allowing data between the at least two versions topic map meta-model of the enterprise meta-models within the enterprise model to be correlated.

11. The program product of claim 10, further comprising:

program instructions, stored on at least one of the one or more storage devices, to create a version of a topic map meta-model including a topic map based index and instance ontology, for each version of the enterprise meta-model within the enterprise model, each version of the topic map meta-model being in a separate scope; and

program instructions, stored on at least one of the one or more storage devices, to store each version of the topic map meta-model in a repository.

12. The program product of claim 10, further comprising:

program instructions, stored on at least one of the one or more storage devices, to create resource description framework triples for each version of the topic map meta-model; and

program instructions, stored on at least one of the one or more storage devices, to store the resource description framework triples into a repository.

13. The program product of claim 10, further comprising:

program instructions, stored on at least one of the one or more storage devices, to recursively create a merged topic map in a scope, the merged topic map including a topic map based index and instance ontology for each additional version of the enterprise meta-model; and

program instructions, stored on at least one of the one or more storage devices, to store the merged topic map into a repository.

14. The program product of claim 13, wherein the scope of the merged topic map is a scope newer than a scope of a previous version of the merged topic map.
