-incdeg template: ster?clnt=<name|pass>&com=incdeg&usr=<usr>&<str_1>=<step_1>&... Order of query params is not important: updates of degrees are performed in the order they appear in the request, however the changes are of accummulative nature, so the final result is the same. descript: for the specified user, the relevence degree for each specified stereotype is increased by x (decreased if x is negative), where x is the step corresponding to that stereotype. Rows with NULL degrees are not affected. If no matches are found, or if all matches have NULL degrees, no records will be updated (200 OK will still be returned). If any <step_i> parameter cannot be converted to numeric, 401 is returned. If the error code 401 is returned then no updates have taken place in the DB. example : ster?clnt=name|pass&com=incdeg&usr=john&visitor=-0.1&expert=1 returns : 200 OK, 401 (fail, request error), 501 (fail, server error) 200 OK : in this case the response body is as follows <?xml version="1.0"?> <?xml-stylesheet type="text/xsl" href="/resp_xsl/rows.xsl"?> <result> <row><num_of_rows>number of relevant rows</num_of_rows></row> </result> comments: the reference to the xsl file allows to view results in a web browser. In case the response body is handled directly by an application and not by a browser, this reference to xsl can be ignored.
