Abstract

The generation of metadata shall be simplified. Therefore, a method is presented in which a metadata-template is filled with selected essence and MD-links obtained from a list of links to essence and/or a list of current metadata. Furthermore, it is possible to obtain the MD-links from further metadata or essences directly or indirectly linked with the selected essence.

Claims

1. A computer based method for processing multimedia data including the steps of:

providing at least one selected essence data, wherein essence data represents information being directly perceptible by a user,

providing a metadata template to be used to form at least a first metadata,

providing at least one of a list of links to a plurality of second essence data and a list of a plurality of second metadata,

determining at least one of;

that at least one metadata link is a link and is in the list of links that points to said selected essence data and that at least one of the second metadata has a metadata link pointing to said selected essence data, and

forming said at least first metadata on the basis of said at least one selected essence data and metadata associated with said determined metadata link by applying said metadata template.

2. Method according to claim 1, wherein said at least first metadata is formed by using in an MD-essence space of said metadata template metadata essence associated with said determined metadata link.

3. Method according to claim 1, wherein the determined metadata has at least one second metadata link, and wherein the first metadata is formed by adding said at least one second metadata link into an MD-link space of said metadata template.

4. Method according to claim 1, wherein the determined metadata has at least one second metadata link pointing to at least one third metadata, and wherein the third metadata is used for forming said first metadata.

5. Method according to claim 1, wherein the step of forming said at least first metadata is performed by a graphic user interface.

6. A computer based device for processing multimedia data comprising:

a first storing means for providing at least one selected essence data, wherein essence data represents information being directly perceptible by a user,

second storing means for providing a metadata-template to be used to form at least a first metadata,

third storing means for providing at least one of a list of links to a plurality of second essence data and a list of a plurality of second metadata,

first processing means connected to said first, second and third storing means for determining at least one of;

said metadata link is in the list of links points to said selected essence data, and said at least one of the second metadata has a metadata link pointing to said selected essence data, and

second processing means connected to said first, second and third storing means for forming said at least first metadata on the basis of said at least one selected essence data and metadata associated with said determined metadata link by applying said metadata template.

7. Device according to claim 6, wherein said at least first metadata is formable by using in an MD-essence space of said metadata template metadata essence associated with said determined metadata link.

8. Device according to claim 6, wherein the determined metadata has at least one second metadata link, and wherein the first metadata is formed by adding said at least one second metadata link into an MD-link space of said metadata template.

9. Device according to claim 6, wherein the determined metadata has at least one valid second metadata link pointing to at least one third metadata, and wherein the third metadata is used for forming said first metadata.

10. Device according to claim 6, further including a graphic user interface connected to said first and second processing means for forming said at least first metadata.
