[CWB] Set up images in text metadata

[Uhrig, Peter]

Hi Stefan,

"image:" was introduced by Andrew in CQPweb as a visualization prefix, see page 72 in http://cwb.sourceforge.net/files/CQPwebAdminManual.pdf

Best,
Peter

I tried to give cqpweb access to the images with "sudo chown -R root:www-group /var/cqp/upload/covers/" but there's something wrong with the path: When I try to open an image in the installed metadata cqpweb gives me "The requested URL was not found on this server".

The image link isn't handled by CQPweb but rather passed through to the client browser.  So you need to provide a public URL (i.e. http: or https:) where the browser can download the image file.

"image:" isn't a valid URI scheme as far as I know – where did you find this format?

The usual solution is to make the image files available on your Web server (possibly password protected) independently of CQPweb, and then construct appropriate URLs and insert them in the corpus metadata.

Best,
Stefan
