hello there
<whikloj>dojobo: hi10:55
<dojobo>i need to develop a metadata store for minting DOIs with datacite, and i'm considering different options, including fedora10:58
* peichman joins
<acoburn>dojobo: what is the scale of data you expect to support?11:00
<dojobo>we have a couple of quarterly publications (whose metadata i can get from a mysql db) and lots of telescope data (whose metadata i can get from a sybase db... i think)
so the bit i need to make will gather these, put them into datacite xml, choose a DOI, submit to datacite for registration via API
and serve pages that the DOIs will resolve to11:01
acoburn, hard to say, to be honest i don't have a real sense yet of the scope of the telescope data, we're still in a very exploratory phase11:02
and i started by focusing on the publications, since they're frankly easier :P and it DOIs were first requested in that context
i think it's a lot of data, it has to be. it's a question of how we're going to segment it for DOI purposes really11:03
also, we're expecting to have a feature that lets a researcher mint a DOI on-the-fly representing a retrieved dataset11:04
(not right out of the gate, of course)
something like this http://archive.stsci.edu/doi/search/11:05
<awoods>dojobo: Sounds interesting. Do you have a specific question about how Fedora could support your use case?11:06
<acoburn>dojobo: if I understanding this correctly, you would store the telescope data as a large binary object in Fedora with appropriate metadata attached (including the DOI)
* bseeger joins
<dojobo>so far i've been trying to decide on a db (postgres? mongodb?) and planning to probably write it all in php, but then i thought i might be better off with an existing repo system11:07
awoods, i guess just curious if this sounds like a good application for fedora
acoburn, actually, i don't anticipate storing the telescope data itself, since the org already has a provision for that
<awoods>dojobo: Even if you do not store the telescope data within Fedora, you have the option of linking to it: https://wiki.duraspace.org/display/FEDORA4x/External+Content11:08
<dojobo>ah, nice :)11:09
<acoburn>dojobo: as for whether this is a good use for Fedora, I think it depends on how you view the metadata of your resources and what you plan to do with it11:12
dojobo: fedora is first and foremost an object repository with strong guarantees about durability
dojobo: as such, it doesn't support the sort of ad-hoc query functionality of a RDBMS11:13
<dojobo>ahh, something i've been wondering about
although i see solr can be used in conjunction with it
<acoburn>dojobo: of course, that doesn't stop you from indexing the content into an external application
dojobo: yes, exactly
<dojobo>i actually discovered fedora through hydra ;)11:14
<acoburn>dojobo: you can index to whatever makes sense for your application: a triplestore, a solr index, a riak backend, a storm topology, whatever you want...
dojobo: that way, you let Fedora do what it's good at (storing and describing resources) and the other applications do what they're good at11:16
dojobo: it also means the fedora application doesn't need to do everything for everyone :-)
<dojobo>makes sense
* jrgriffiniii leaves11:17
<dojobo>i think i'm going to do some more reading to think about this, but i like what i hear so far :)11:19
also want to play with the vagrant box etc
<acoburn>dojobo: great, and feel free to ask questions here or on the fedora-tech list. Also, everyone is welcome to join the weekly phone calls 11 am (ET)11:20
<dojobo>oh, that's great
thanks for being so welcoming :)

<awoods>acoburn: that is great
<acoburn>awoods: yeah, we should do the same thing for fcrepo-camel-toolbox
awoods: related to your earlier comment, jenkins actually _does_ successfully build. I can't say that I understand why, though12:03

<awoods>acoburn: I was wanting to test your fcrepo-camel updates in the context of fcrepo-camel-toolbox...14:11
<acoburn>awoods: can you clarify that?
<awoods>acoburn: Is the best way to do that by updating the toolbox fcrepo-camel version from 4.4.1 to 4.4.2-SNAPSHOT and rebuilding?
<acoburn>awoods: yes, that would be the best way to test it14:12
<awoods>acoburn: thanks... I will give it a try

awoods: but I'm happy to merge it14:51
awoods: the point of the PR was to remove the pidMinter bean from the spring config, but that's already gone
awoods: it does make the component scan portion cleaner, which is useful14:52

acoburn: removing the UUIDPidMinter config element.14:53
<acoburn>yes, but if you rebase the PR on master, you'll find that that line has already been removed
<awoods>acoburn: oh...
acoburn: ok, we may as well merge the simplified component scanning.14:54
