Abstract

A method and system for managing semantic and syntactic metadata. Heterogeneous data is received. After the heterogeneous data is received, the semantic metadata associated with the received heterogeneous data is captured and syntactic metadata associated with the received heterogeneous data is captured. The semantic metadata describes contextually relevant or domain-specific information about data based on an industry-specific or enterprise-specific metadata model or ontology. The syntactic metadata included grammatical rules and structural patterns governing an ordered use of formats and arrangement pertaining to specified data. The received heterogeneous data and said captured semantic metadata and said syntactic metadata are logically linked. The heterogeneous data is stored in a repository.

if having determined that said received heterogeneous data does not utilize the standardized syntax, then receiving at least one syntax response from an end user and storing in said library said at least one syntax response as a unique syntactic metadata template.

3. The method of claim 2, wherein said determining determines that said received heterogeneous data utilizes the standardized syntax, wherein each response of said at least one syntax response corresponds to a unique question of at least one syntax question sent to the end user, and

wherein each question of said at least one syntax question relates to syntactic attributes of said received heterogeneous data.

4. The method of claim 2, said method further comprising:

initiating a data parser to capture both said semantic metadata associated and said syntactic metadata associated with said received heterogeneous data, said capturing utilizing both said semantic metadata template and said syntactic metadata template.

5. The method of claim 1, said capturing said semantic metadata comprising prior to having determined whether said received heterogeneous data utilizes the standardized syntax:

determining that said received heterogeneous data was not generated by a machine;

after having determined that said received heterogeneous data was not generated by the machine, sending one or more questions to said end user, each question of said one or more questions relating to semantic attributes of said received heterogeneous data; and

receiving at least one response from said end user, each response of said at least one response corresponding to a unique question of said one or more questions.

6. The method of claim 1, said capturing said semantic metadata comprising prior to having determined whether said received heterogeneous data utilizes the standardized syntax:

determining that said received heterogeneous data was generated by a machine;

after having determined that said received heterogeneous data was generated by the machine, determining that said semantic metadata associated with said received heterogeneous data does not reside in said library, said library comprising at least one semantic metadata template;

after having determined that said semantic metadata associated with said received heterogeneous data does not reside in said library, sending one or more questions to said end user, each question of said one or more questions relating to semantic attributes of said received heterogeneous data;

receiving at least one response from said end user, each response of said at least one response corresponding to a unique question of said one or more questions; and

storing in said library said at least one response as a unique semantic metadata template.

7. The method of claim 1, said capturing said semantic metadata comprising prior to having determined whether said received heterogeneous data utilizes the standardized syntax:

determining that said received heterogeneous data was generated by a machine;

after having determined that said received heterogeneous data was generated by the machine, determining that said semantic metadata associated with said received heterogeneous data resides in said library, said library comprising at least one semantic metadata template; and

after having determined that said semantic metadata associated with said received heterogeneous data resides in said library, retrieving from said library a semantic metadata template corresponding to said semantic metadata associated with said received heterogeneous data.

20. The method of claim 1, said semantic metadata describing domain-specific information about data based on an industry-specific or enterprise-specific metadata model or ontology.

8. A computer program product, comprising a computer-readable hardware storage device having a computer-readable program code stored therein, said computer-readable program code containing instructions that when executed by a processor of a computer system implement a method for managing semantic and syntactic metadata, said method comprising:

said processor receiving heterogeneous data;

after said receiving, said processor capturing semantic metadata associated with said received heterogeneous data, said semantic metadata describing contextually relevant or domain-specific information about data based on an industry-specific or enterprise-specific metadata model or ontology;

after said receiving, said processor capturing syntactic metadata associated with said received heterogeneous data, said syntactic metadata including grammatical rules and structural patterns governing an ordered use of formats and arrangement pertaining to specified data;

said processor logically linking said received heterogeneous data and said captured semantic metadata and said syntactic metadata; and

said processor storing said heterogeneous data in a repository.

9. The computer program product of claim 8, said capturing said semantic metadata comprising:
