Hi Fiona!
I am not a DSpace committer, just adapting it for the internal needs of
Belgium PoisonCentre.
At my best knowledge, you can alter metadata in the item metadata table
but, if the field is indexed by Lucene (fields indicated in the advanced
search form), then you will have to reindex the whole base. If it is an
enormous one, you could index differently for an added field than for a
(re)moved one.
If your IT staff is more confortable with SQL, they do not have to
refrain using it (except for the Lucene question) but using the "Item"
class for updating, if you are using Java, is not that bad.
I have submitted an improved version working better for import/re-import
of metadata. Please let me know if you want a copy of it (compatible
1.4.1 - 1.4.2).
Have a nice day!

Dear DSpace Experts,
I have been asked by our staff if there are objections to undertaking
bulk changes in the dspace database using Postgres commands, i.e
directly modifiying particular tables to insert/update data. Their
feeling is that doing records one at time is not what computer systems
are about.
In particular they are looking at making bulk changes to some items
which contain a dc.rights field, where they need to add a dc.rights.url
field corresponding the Creative Commons licence the item has.
There has been some testing done on a minor test machine and so far
nothing appears to have gone wrong as such, but I am concerned that
often problems are not always spotted. I am fairly conservative in these
things.
Has anyone tried to do this?
Has anyone an opinion on doing this?
Thanks,
Susan Chapman
