Abstract

A method is provided that includes receiving a first triple including a subject, predicate and object, where the object is of a literal-type. For the first triple, then, the method includes identifying a subtype of the object; semantically marking the object with the identified subtype, including generating second and third triples; and storing the second and third triples in a triple store. In this regard, the second triple includes the subject and predicate of the first RDF triple as the subject and predicate thereof, and the third RDF triple includes the object of the first RDF triple or a representation of the object of the first RDF triple as the object thereof.

Claims

1. An apparatus comprising:

a processor configured to receive a first resource description format (RDF) triple for storage in an RDF store, the first RDF triple including a subject, predicate and object, the object comprising a uniform resource identifier-type (URI-type) or a literal-type object, wherein, for the first RDF triple including a literal-type object, the processor is configured to;

identify a subtype of the object of the first RDF triple;

semantically mark the object with the identified subtype, including being configured to generate a plurality of second RDF triples corresponding to the first RDF triple, the plurality of second RDF triples comprising an RDF triple including the subject and predicate of the first RDF triple as the subject and predicate thereof, and another RDF triple including the object of the first RDF triple or a representation of the object of the first RDF triple as the object thereof; and

store the plurality of second RDF triples in the RDF store.

2. An apparatus according to claim 1, wherein the instructions are further configured to cause the processor to process the object of the first triple, including being configured to cause the processor to one or more of compress, reformat or encrypt the object, the representation of the object comprising the processed object or a representation thereof.

3. An apparatus according to claim 2, wherein the instructions being configured to cause the processor to process the object further includes being configured to cause the processor to archive the processed object at a location in storage external to the store, the representation of the processed object comprising the storage location.

4. An apparatus according to claim 1, wherein the instructions are further configured to cause the processor to process the object of the first triple, including being configured to cause the processor to archive the object at a location in storage external to the store, the representation of the object of the first triple comprising the storage location.

5. An apparatus according to claim 1, wherein the instructions being configured to cause the processor to identify a subtype further includes being configured to cause the processor to identify one or more other properties of the literal-type object, and

wherein the instructions being configured to cause the processor to semantically mark the object includes being configured to cause the processor to semantically mark the object further with the identified one or more other properties, the processor further being caused to generate, for each of the identified one or more other properties, an additional triple including the respective other property as the object thereof.

6. An apparatus according to claim 1, wherein the instructions being configured to cause the processor store the second and third triples includes being configured to cause the processor to store the second and third triples in lieu of storing the first triple in the store.

7. An apparatus according to claim 1 further comprising:

a memory configured to implement the store.

8. An apparatus comprising:

a user input interface, a communication interface, and a processor configured to access instructions from memory, the instructions being configured to cause the processor to;

receive, through the user input interface, an instruction to process an object located in the apparatus;

generate a first triple including a subject, a predicate and the object;

send, through the communication interface, the first triple to a remote apparatus; and

receive, through the communication interface, a representation of the object.

9. An apparatus according to claim 8, wherein the instructions are further configured to cause the processor to:

semantically mark the object, including causing the processor to generate;

a second triple including the subject and predicate of the first triple as the subject and predicate thereof, and

a third triple including the object of the first triple or a representation of the object of the first triple as the object thereof; and

store the second and third triples in a triple store.

10. An apparatus according to claim 8, wherein the representation of the object comprises a storage location.

11. An apparatus according to claim 10, wherein the instructions are further configured to cause the processor to remove the object from the apparatus.

12. A method comprising:

receiving a first triple including a subject, predicate and object, the object comprising a literal-type object;

identifying a subtype of the object of the first triple;

semantically marking the object with the identified subtype, semantically marking the object including generating;

a second triple including the subject and predicate of the first triple as the subject and predicate thereof, and

a third triple including the object of the first triple or a representation of the object of the first triple as the object thereof; and

storing the second and third triples in a triple store.

13. A method according to claim 12 further comprising, for the first triple including the literal-type object, processing the object of the first triple, including one or more of compressing, reformatting or encrypting the object, the representation of the object comprising the processed object or a representation thereof.

14. A method according to claim 13, wherein processing the object further comprises archiving the processed object at a location in storage external to the store, the representation of the processed object comprising the storage location.

15. A method according to claim 12 further comprising, for the first triple including the literal-type object, processing the object of the first triple, including archiving the object at a location in storage external to the store, the representation of the object of the first triple comprising the storage location.

16. A method according to claim 12, wherein identifying a subtype further comprises identifying one or more other properties of the literal-type object, and

wherein semantically marking the object comprises semantically marking the object further with the identified one or more other properties, semantically marking the object further including generating, for each of the identified one or more other properties, an additional triple including the respective other property as the object thereof.

17. A method according to claim 12, wherein storing the second and third triples comprises storing the second and third triples in lieu of storing the first triple in the store.

18. A method according to claim 12 further comprising:

providing a memory configured to implement the store.

19. A computer-readable storage medium having computer-readable program code portions stored therein, the computer-readable program code portions comprising:

a first executable portion configured to receive a first triple including a subject, predicate and object, the object comprising a literal-type object;

a second executable portion configured to identify a subtype of the object of the first triple;

a third executable portion configured to semantically mark the object with the identified subtype, including being configured to generate;
