Abstract
An index structure of metadata provided for searching for information on contents, a method for providing indices of the metadata, and a method and an apparatus for searching for the metadata using the index structure of the metadata are provided. The index structure of the metadata includes a list of keys composed of predetermined fields of the metadata, wherein the list contains therein location information of the fields in the metadata, wherein at least a part of the location information is expressed as predetermined code.
Claims53
An index structure of metadata comprising:
- a list of keys composed of predetermined fields of the metadata,
- wherein the list contains therein location information of the fields in the metadata, and
- wherein at least a part of the location information is expressed as a predetermined code.
A method for providing a metadata index including a list of keys composed of predetermined fields of the metadata, comprising:
- providing the predetermined fields of the metadata to the list of the keys;
- wherein the list includes location information of the fields in the metadata,
- wherein at least a part of the location information is expressed with a predetermined code.
A method of searching metadata, comprising the steps of:
- (i) determining location information of a field of search conditions input by a user, in the metadata;
- (ii) searching a key containing a predetermined code as location information, where at least a part of the location information is defined as the predetermined code;
- and
- (iii) extracting a concerned metadata by use of the searched key.
An apparatus for searching metadata, comprising:
- an input unit allowing a user to input search conditions;
- and
- a control unit determining location information of a field of the search conditions input by the user, in the metadata, searching a key containing a predetermined code as location information, where at least a part of the location information is defined as the predetermined code, and extracting the concerned metadata by use of the searched key.
48 The apparatus as claimed in claim 47, wherein the representative key value comprises at least one of a maximum value, a minimum value or an intermediate value among the values within the predetermined range.
Dependencies are inferred from the claim text.
