I understand the idea of curiosume (as far as I know there is not working application yet) to be a collaboration platform where people can state something about
1) being associated with certain topics (wikipedia entries)
2) and whether they want to teach others about a certain topic or collaborate with others or learn from others about it.
My concept about how this could be implemented using a blockchain:
A curiosume profile would be an advanced user issued asset which is defined by the two points above (1 and 2).
At the very end of this video
https://www.youtube.com/watch?t=2601&v=CMeQ_rNkGKU Dan Robles also talks about how this could be used for matching job descriptions and contractors to take the job. He says: A curiosume profile (short: curiosume) could not only represent the skillset of a person but also a job description (e.g. c++, database systems, crypto currencies, team leadership, ability to learn, and whatever other skills are needed for the job). This list of attributes that all would have an entry in the wikipedia (public one or a private customized one) would all have been assigned an identifier and the set of these identifiers would make up the curiosume profile that represents a job description.
The functionality blockchain wise that would be necessary to make this work would be an automated matching or suggestion algorithm that matches job profiles and contractor profiles on the blockchain.
This is just wild thinking, public brainstorming and I even can't see atm what advantages it would have to realize it via a blockchain than with a centralized database. I also don't know whether the amount of information (all the identifiers) of the profiles wouldn't be too big for a user issued asset / transaction as they exists today in Bitshares.
