> The nuxeo tag library need an an upgrade for the outputFile and outputImage
> components and matching URL filters to be able to generate / handle URLs to
> directly access the content of a blob. Sample expected URLs are:
> http://server.domain:port/nuxeo/nxdoc/demo/a8865360-a076-4a31-890d-6d1bb14f1e1b/download_blob/file/content/3/filename.doc
> or
> http://server.domain:port//nuxeo/download_blob/demo/a8865360-a076-4a31-890d-6d1bb14f1e1b/file/content/3/filename.doc
> where:
> - 'file' is the schema name of the blob to download
> - 'content' is the field name of the blob to download
> - '3' is the index of the blob to download in case 'file.content' is a
> complex field (optional)
> - 'filename.doc' is the filename of the blob if any (optional)
> Why we need a GET URL and not a js postback (like h:commandLink component):
> - we will need to generate HTML tags such as <img
> src="/my/get/url/to/image.png" alt="image title"/> so that browsers can
> download blobs to be used as images (for thumbnails of content and so).
> - have meaningful URL so that google can index attached files (PDF, doc,
> ...) to be ready the day nuxeo 5 wil be used for web content management.
> We also need similar URL filters and JSF tags for the "edit online" and "pdf
> preview" links.
