| + | An ''[[XMP]] Sidecar File'' is a file containing serialized metadata related to a document. Sub-optimal for obvious reasons, these are used by tools, including [[liblicense]], when the file format does not support direct embedding. |

| − | This is a specification for companion file metadata. This takes the form of an associated [[RDF]] or [[XMP]] file that has metadata and licensing that is included along with a work.

| − | | |
| − | Thus if you had a file such as the one referenced, '''barcode_ean13.svg''', one would create a file '''barcode_ean13.rdf''' that would contain the following. The rdf:about reference in <Work /> tag is very important for linking both relative and absolute information to a file.

| − | Similarly, if you want to use [[XMP]] for the companion file, this is acceptable as well. [[#XMP Sample|See the example]].

| − | It is impractical to embed metadata in some file formats, and, it should be optional to store metadata outside of a file. So we need a specification for a "companion" metadata file that would define license and other metadata information. This could take

| − | === Implementations ===
| |
| − | | |
| − | * [http://www.openclipart.org/ Open Clip Art Library] puts RDF metadata and licensning info into a package of clip art that is named with *.rdf.
| |
| − | * Please add your implementation here :)

| − | === Examples ===
| |
| − | | |
| − | * See [http://openclipart.org/wiki/index.php/Metadata_Discussion this page detailing the Open Clip Art Library's solution].
| |
| − | * See the [[#Sample]] above to figure out how to connect your file with CC licesning and metadata.
