DDD

Aquest Nadal m'he estat creuant uns missatges amb l'Alexander Wagner, que coordina els Invenios del «CSIC alemany», i em va desaconsellar la migració a la 1.2. Copio algunes de les seves frases literals:

For us 1.0->1.1 was quite an effort, however, the 1.1.x series worked quite well. At least so far. We played quite a bit with 1.2 but we had to five this up as we ran into way to many issues. Performance, OAI, search. Some of them due to solutions we invented to get 1.x flying (collection restrictions eg.) that we'd need to re-invent for 1.2. So the plan would be to dive directly into the shiny new world of 3.x, which is basically a totally new start from scratch including migration and not an update. Any plans on your end with regard to that?

Quan li vaig demanar si tenia informació més detallada, em va concretar:

In short what we found:

• Result display may be very slow as every HB get an "Edit this record" calculated online upon display depending on the user to view the record. You can work around this by switching this off which helps a lot.
• If you have many closed collections, result display may be very slow again due to calculation of display rights.
• The climb down into the subcollection seems to slow down result display at least in our case (CDS doesn't show it). This may be connected with the former issue.
• As all our records belong to at least one restricted collection default settings do not show any search results at all for guests.
• Similarly, as we use http-queries against our systems for websubmit (JSON returns for normalized values) which are anonymous queries we do not get results.
• We did not get authority search to work as expected, though all should be in place as Tibor told me (I didn't work on this myself, probably it's just a configuration issue. Then at least it is not obvious how to do it properly.)

El motiu que havia de ser més interessant, el control d'autoritats, no sembla que sigui suficient per trobar-nos amb els inconvenients que els col·legues alemanys s'han trobat, no creieu?
