- How will we implement tags? As plain text that is appended to slide revisions and decks (e.g. tags: [mathematics, fibonacci, ...] or as URIs that are already linked to further knowledge (RDF)?
- for the second option: How do we make sure that the concept is distinct, so we can link it to further knowledge? E.g. someone tags a slide with "bench" .... did he meant furniture or law (maybe not the best example in English)
- how do we handle distinct concepts in case we /topics in case we can't distinguish topics (so we can't decide whether to link to bench (furniture) or bench (law))?
- for the second option: How do we save these tags? As part of the slide model in the MongoDB or as a separate DB (e.g. a Graph DB - read next section)
- for the second option: Do we want to show to users that they are working with RDF (e.g. by showing them URIs)?
