The CombineFormatizer contains methods to obtain format URIs for certain file types.
Within the COMBINE community, file formats are usually expressed as URIs, e.g. in combinearchive:wiki. That is, an SBML file may for example be of format
http://identifiers.org/combine.specifications/sbml. This often makes things extra complicated and, thus, we developed the CombineFormatizer.
The Formatizer class provides some methods to retrieve a format given a file:
If you just have a file extension you may pass it to
Formatizer.getFormatFromExtension (String) JavaDoc:
File f = ... String extension = f.getName ().substring (f.getName ().lastIndexOf (".") + 1); URI format = Formatizer.getFormatFromExtension (extension);
That is obviously not the best method, but it might be a good start.
The CombineFormatizer is also able to guess formats from media types using
Formatizer.getFormatFromMime (String) JavaDoc:
File f = ... String mime = Files.probeContentType (f.toPath ()); URI format = Formatizer.getFormatFromMime (mime);
You can also pass a file object to
Formatizer.guessFormat (File) JavaDoc:
File f = ... URI format = Formatizer.guessFormat (f);
