jakob, I haven't yet had time to look at your SOBR, but I am meeting soon with some folks to talk about a kind of "RDA lite" -- the goal being to build up a data structure using RDA but starting with a bare skeleton rather than the whole 1,300 properties. (And I'm pretty sure it will not be the same as RDA core.) If we come up with anything concrete from this first meeting I will post it here and we can compare to your schema. This one will have the library catalog "bias" but that simply means that it may serve the library cataloging function. kc Quoting Jakob Voss <jakob.voss@gbv.de>: > Tim Hodson wrote: > >> If the BL uses a vocabulary that imposes restrictions on how the term >> is used those restrictions might mean that linking to outside sources >> becomes more difficult, as the scheme definition starts to imply >> things about the data that are not meant. >> >> Much better is to start simply with the easy things to describe, but >> model the domain in a way that is extensible. > > I fully agree.
