New Head of Science askes me questions about why we have data in Europeana & GBIF when we have data on our catalogue.
1
These are the questions I am asked.
2
So there are some differences in what each aggregator records.
3
Point 1 - Obvious but, Point 2 - but often this sort of request ends up channelled through the “marketing department” rather than getting to database administration. Point 3 – again obvious.
4
At times there is always something broken or not fully functioning and I wanted this to be a positive presentation, not there is a problem last year with Europeana or our own catalogues.
5
I’d like to put up the following caveat.
6
To start with lets look at Europeana
7
Not going to just read out the figures. But going to try and point out interesting / points facts So lets start with noting ave duration of visit 21 mins that’s research not just browsing.
8
As expected lots of EU countries, but the others reflects what data we have in Europeana i.e. types & Arabian data. We not told anyone in the UAE that they can access our data via Europeana so the use must have just grown out of the data.
9
Now GBIF
10
GBIF don’t record searches anymore now only record downloads Herbarium many more searches (more data) Couple of points here - ! Just how much data was downloaded – not searched for but downloaded. 13 million records in a month that appears quite a lot to me. Second point. But what I had not expected was the ave number of records I had not anticipated that 8K – skewed by the complete downloads even without them 4 ½ K These 6 with complete downloads - What are they after? 81% of searches are taxon searches – to be expected – the format of GBIF is a
11
RBGE catalogues. Produced every evening, so a much more frequent update cycle.
12
Still a lot of searches, but a much less surprising number compared to GBIF.
13
By far the biggest user of the catalogue is internal (which is odd as we have a database for use). This averages out at 248 internal searches a day (it’s actually a little higher because being Scotland we had Jan 1st and jan 2nd as holiday. The other interesting thing is the searches are international not EU based.
14
Downloads A much better number of downloads items.
15
China is downloading twice as much as anybody else, Two ways too look at this 1. That’s an part of the world we are doing research and we have very good
collections so that’s to be expected.
2. Somebody over there is stealing our stuff.
Again the internal use is high, but that is the only way to access the images.
16
Initially my plan was to do a number of direct comparisons and try to find some common metrics. But this has proved hard and I feel may not be useful. Each aggregator has a different focus for a different audience and therefore a different search mechanism, which in turn influences the results.
17
Even here with the job titles you can see the differences in scope and intent for the datasets. Neil Bates <[email protected]> GBIF Helpdesk <[email protected]> or Andrea Hahn <[email protected]> Martin Pullan <[email protected]>
