[EP-tech] Re: Editable eprints behind firewall with read-only copy in the DMZ

Thanks! I was thinking selective database replication & filesystem syncs; your idea might be less work.

What did you use to determine which items needed to be exported / imported? I see there are a series of "lastmod_<timeperiod>" columns in the "eprints" table; did you use those, or something else, or a combination?

I appreciate your input.

Dan

hi dan

we made once (3.x ?) a proof-of-concept with 3 EP repository, each on
a own virtual maschine and in different networks.

1st repo was for ingest.
with cron the ingested item where exported (ep-xml) and imported in
2th repo by bash scripts.

2th repo was dlza with very restriced access

3th repo was public: items worthily for public were marked in 2th repo
and also by cron copied to 3th.

it was working but:
since we used ep-xml-with-embedded-full-text for import/export, adding
an item in repo 3 blows up the ep-item-history with the binary code of
the fulltext. and also when there where any modification on 2th repo,
the changed metadata + the full text again was added in the
ep-item-history on repo 3.

after soon the history couldn't be used because of the hugh data was send
and as i remember, the proof-of-concept was abandoned

????
i would be interested to know the best way to copy items from one
ep-repo to an other ep-repo.
????

thanks
bye
