Tags are created on use, but new members of Robotics often don't have the 150 reputation currently required to create new tags, so rely on on those of us with the privilege to add appropriate tags to questions, either as suggested edits, or direct edits (with Edit questions and answers privilege, currently at 1000 reputation).
From a few quick searches, it looks like it would be a good idea to use tags to separate out the two libraries and avoid confusion. As such, as a domain expert, I would be happy for your to review likely questions and add tags as appropriate.
There are currently 126 questions tagged with the matlab tag, and doing a search for
corke currently pulls up 26 questions, not all of which are tagged with the matlab tag. Meanwhile
matlab toolbox shows 79 results,
matlab toolbox corke finds 7 and the robotics-library tag also shows 7.
At the moment, if you start typing
matlab in the Tags textbox, only matlab gets suggested, so I would suggest adding
matlab- to the start of both toolbox tags. I don't think we need
robotic in there as our site is Robotics. Obviously
toolbox needs to be in there, as does something to differentiate your toolbox from the the mathworks one. I think
corke is fine for question about your toolbox, but I'm not sure about the other.
My suggestions would be matlab-corke-toolbox and either matlab-mathworks-toolbox, matlab-system-toolbox or matlab-toolbox.
If you can add these tags to existing questions, I would be happy to Approve tag wiki edits (currently 1500 reputation) on your suggestions, though it probably won't be long before you hit that reputation anyway. *8')
It would also be worth adding a mention of the other toolbox to both tag wikis so that you can't read the description of one without seeing a mention of the other. This is especially important if we go for matlab-corke-toolbox and matlab-toolbox as we don't want people accidentally selecting one tag when then intended to select other.
Note that once we have differentiated tags, we can always add synonyms like robotics-toolbox and robotics-system-toolbox later.
One final point that is worth mentioning are the suggestions on What kind of behavior is expected of users? and How not to be a spammer.
You should disclose your affiliation in your answers, so now might be a good time to edit your answers to mention you are the developer of the software.
As it is in your interest and the sites to have well tagged questions, I'm glad that you brought this up, I'm happy to let you know that you already have the ability to fix most of this yourself (the question tags), and I'll happily support you with few bits you can't fix without help (the tag wiki edits).
