Wrong concept codes in keywords #32
Description
We have strange URIs for concepts in the sshoc-keyword vocabulary that do have a space in the label, see e.g. https://marketplace.sshopencloud.eu/tool-or-service/1U5uMh and the keyword "word processing" (which could also have a line break inside, looking at the weird representation in the frontend) whose url is "https://vocabs.dariah.eu/sshoc-keyword/word%20processing". But such concepts are not able to be resolved due to the space character. This was the reason, that when a user adds a new concept which has a space character in the label the url will be camelCased. I'm not sure, why this is not the case for "word processing" - looking at the information contributors it is most probably a problem coming from the ingest pipeline. There are some other concepts that look the same.
Need to find out, how such a URI could have been created. We also like to get rid of them as they do not resolve at our vocabulary server.
