[CWB] CQPweb - managing metadata

[Claudia Borg]

Hi Andrew, Thanks for your reply. Some more questions from my side to help
me understand better:

metadata can be extra information about the corpus (e.g. URL, author) and
not linguistic information present in the text, correct? Linguistic info are
the p-attributes, and the structure of the text (chapters, ect) are the
s-attributes - correct?

re removing text_id and text_lang - I've done that and now getting a
different error :(

What I did:
placed a new file in the upload section
installed a new corpus using this file leaving default s- and p-attributes
clicked on design and insert a text-metadata table link
left all as is on the form and just clicked the minimalist metadata button
at the bottom - the result is this:

*Error message*
**** CQP ERROR ****
CQP Error:
Corpus ``EXAMPLESIMPLE'' is undefined



I'll try to have a look at the code - I suspect that the problem is actually
in the previous step when installing a new corpus - how can I confirm that a
corpus has been indeed installed correctly? At this stage all I notice is
that in my /var/www/ I have a new folder for the corpus, with some php files
inside it - apart from that, I don't see any other changes. When using the
terminal version, cwb-encode and cwb-make create a bunch of additional
files....but I am not seeing this happening in the web version - how can I
check this? ....in the meantime, help is much appreciated!

Claudia
