    hello again
    thanks @kehh ... it was very helpful, i'm now trying to use simple api
    i've figured out how to do that so far... the only problem is how to get all object representations
    Stefan
    @stefankeidel
    They have a few media examples in there, for instance here: https://github.com/rwahs/providence-configuration/blob/master/conf/services.conf#L45

    i tried these, but i get only primary image

    @stefankeidel
    I talked to @kehh about that exact issue just this week I think

    @tsitsibau
    i tried something like this...
    Repres = ""<unit relativeTo="ca_object_representations" filterNonPrimaryRepresentations="0" delimiter="," returnAsArray="1"><unit>^ca_object_representations.media.original%returnURL=true</unit>|<unit>^ca_object_representations.media.preview170%returnURL=true</unit></unit>"",
    but i am still getting 1 image
    Stefan
    @stefankeidel
    Again, this option is for ca_objects units only right now
    tsitsibau
    @tsitsibau
    let me make this clear... because i'm confused
    i use simple api... and i want to fetch an object's information
    and display all the representations of this object
    can i do this?
    tsitsibau
    @tsitsibau
    i use the following without success 
            Repres = <unit relativeTo="ca_object_representations" filterNonPrimaryRepresentations="0" delimiter="," returnAsArray="1"><unit>^ca_object_representations.media.original%returnURL=true</unit>|<unit>^ca_object_representations.media.preview170%returnURL=true</unit></unit>,
    i also want to find related collections with public access
    and i use the following without success 
            Collection = <unit relativeTo="ca_collections" delimiter="," returnAsArray="1"  checkAccess="[1]"><unit>^ca_collections.preferred_labels.name</unit>|<unit>^ca_collections.collection_id</unit></unit>,

    (it returns all of them)

    Greetings all. I am running two different C/A instances, one of which is a recent copy of the production system. When I run a mapping on the testbed one, it seems to run just fine; however on the production system, I am getting an error. (i.e. cannot create add or update . . . foreign key constraint.) Any suggestions on how to figure out what the difference is?
    I basically created a new mysql db for the testbed database, copied the providence files over to a new folder and updated the setup file

    @stefankeidel
    @sterlingjenson what's the FK error? @tsitsibau Some of these options won't work on units. You don't need to put checkAccess for each individual unit. Just put it in the service definition of the simpleAPI endpoint
    There are working examples here: http://docs.collectiveaccess.org/wiki/SimpleAPI

    Stefan
    @stefankeidel
    Looks like the relationship type you're trying to use is missing
    sterlingjenson
    @sterlingjenson
    ah, I see. for object and collection storage relationships, it will be "related," correct?
    Stefan
    @stefankeidel
    That depends on your profile, but yeah -- that's the default type from base.xml

    @sterlingjenson
    thanks.

    I'm running a data import, and I'm trying to use the option applyRegularExpressions to convert a file name to an object idno. I can't get the regular expression to apply - it is simply importing the file name as the idno. Here's the text of my applyRegularExpressions statement:
    {"applyRegularExpressions": [{"match": "(NYSA_A1810-78_V15_[0-9]{4})_.+", "replaceWith": "\\1"}]}
    Can you tell what I'm doing wrong?

    @collectiveaccess Hi, I have just run git pull again and now when I try to preview a pdf document I get the tool bar at the top of the screen, the thumbnails of the pages on the left hand side of the screen but only the small rotating block in the main screen so some improvement from my previous post.

    @kehh
    @stefankeidel @tsitsibau I had no luck with multiple representations on objects. This is the latest master-fix. Do you want me to file a bug?
    tsitsibau
    @tsitsibau
    @kehh it's really a problem for me.... i'll probably have to use the other api (not simple) just for this... which gives all representations...
    Stefan
    @stefankeidel
    @kehh That option is more or less a hack I added for a very specific use case and it works well for that use case (related objects). We may want to make that available as a more generic feature but there are no plans to do so at this point.
    As usual we welcome any code contributions

    Hi, I'm currently creating an archive management system for a new nuclear archive being built in Wick, Scotland using collective access - on investigation of the current system and data they currently have it seems going forward the best data schema to use for this is a Data Warehouse, is this possible within the Collective Access system? Thank you
    CollectiveAccess
    @collectiveaccess
    What do you mean by data warehouse?
    Are you thinking along the lines of star schemas?
    Bounty2017
    @Bounty2017
    Yes - I essentially want to be able to get all data they have and be able to push all results into one table
    CollectiveAccess
    @collectiveaccess
    You could export data from CollectiveAccess in that form
    but internally it's structured to be a collections database, not an OLAP system
    Bounty2017
    @Bounty2017
    Ahhh okies, thank you
    CollectiveAccess
    @collectiveaccess
    If I may ask what sort of nuclear materials are you cataloguing ? :-)
    Bounty2017
    @Bounty2017
    Haha I could tell you, but then I would have to kill you :P

    @Bounty2017
    So just another question (Just to see if I can get around this a different way) say I have 5 different databases (All have different column names etc) and I created a different data map for each one and imported the data, would I not be able to alter CA to find data, based on individual and all databases? and add new data to a database they selected?

    I've tried setting up Providence. I've succeeded once, but chose an incorrect profile. Deleted all the tables that were created in the configured database. Restarted install procedure, but now the install procedure never finishes (in the end I get a white screen), whatever profile I chose. Am I doing something wrong?
    I also removed everything in the cache directory ut that also doesn't help. Deleted everything in the dir on the www server, re-cloned the repo, same thing happens
    Also, what is the most basic profile to start with?
