Metadata

Metadata. A clear animation explaining metadata (though I’m still confused about some of the icons on the spacecraft!). They’ve also got a link to a metadata creation site (UK use only; Athens authentication required).
I’m still unsure about metadata. It requires effort to create, and it can be open to a lot of personal interpretation. Much as I have a difficulty with tags – forgetting what I’ve used; and it’s just me that’s using it. The more I think about metadata, and the difficulty of getting agreement on what terms should be used, what level is what … I think that it requires a lot of extra input on the individual to create the data. Time which might be better spent on something else…
