[CODE4LIB] METS question for @USE in file/fileGrp
Hi all, According to the METS schema, the USE attribute is A tagging attribute to indicate the intended use of files within this file group (e.g., master, reference, thumbnails for image files). I'm using the mets:fileSec to capture images of a coin within a larger numismatic XML schema. The @USE is an unrestricted xs:string, and this example document - http://fedora.library.northwestern.edu/fedora/get/inu:inu-afrmap-4333843/source- uses recto as a USE for images of a map. By this same token, is it semantically acceptable to have obverse and reverse as a USE? Example: fileGrp use=obverse file use=master file use=reference file use=thumbnail fileGrp use=reverse file use=master file use=reference file use=thumbnail Thanks, Ethan

In the E-R diagram, there is a place for a URL and a chunk of HTML code in each Release entity. I was thinking that is where release-specific information would go, and I will update the document to call it out more explicitly. Thanks again, Lori.

Re: [CODE4LIB] Programmer Orientation to Library/Lib Sci
I'm especially interested in anything which gave you an ah-ha! moment when you were working with library data -- the implicit things which didn't make sense until you knew why those crazy librarians did things the way they did. I'd add that you should be open to accepting that some of those things STILL won't make sense once you know why librarians do things the way they do. Much of what we do indeed simply doesn't make sense -- I mean, we got here somehow for certain reasons, and understanding the history can help understand how we got to where we are, but often where we are is really really unfortunate. (And even many of us librarians don't entirely understand how we got here, if we're under a certain age!) But anyway, you've probably already seen it, but Jason Thomale's Code4Lib Journal article might be useful for providing some of that background for Marc (although I don't neccesarily think his explanation/analysis/solutions are airtight, they're an introduction).

[CODE4LIB] Apps to reduce large file on the fly when it's requested
Dear All, My colleague came with this query and I hope some of you could give us some ideas or suggestion: Our Digital Multimedia Center (DMC) scanning project can produce very large PDF files. They will have PDFs that are about 25Mb and some may move into the 100Mb range. If we provide a link to a PDF of that large, a user may not want to try to download it even though she really needs to see the information. In the past, DMC has created a lower quality, smaller versions to the original file to reduce the size. Some thoughts have been tossed around to reduce the duplication or the work (e.g. no more creating the lower quality PDF manually.) They are wondering if there is an application that we could point to the end user, who might need it due to poor internet access, that if used will simplify the very large file transfer for the end user. Basically: - a client software that tells the server to manipulate and reduce the file on the fly - a server app that would to the actual manipulation of the file and then deliver it to the end user. Personally, I'm not really sure about the client software part. It makes more sense to me (from the user's perspective) that we provide a download the smaller size of this large file link that would trigger the server-side apps to manipulate the big file. However, we're all ears for any suggestions you might have. thanks, ranti. -- Bulk mail. Postage paid.
Re: [CODE4LIB] Apps to reduce large file on the fly when it's requested
I agree that your client software should be nothing more than a link or button in the web browser. As for the server, it sounds akin to image servers that resize on the fly. I would probably just proxy requests to a script or cgi that compresses/converts the files, especially if you're not planning to get a lot of hits per second. If that's not robust enough, there are a number of results from a search for pdf server that might work for you.

Re: [CODE4LIB] Seeking feedback on database design for an open source software registry
Thanks for the reply, Stuart. With the first question, I've updated the diagram to add an Association entity. (Technically, I don't think this is an entity but rather a specialization of a relationship.) This is based off some great work I saw at the NITRC. Take a look at the Associations section of these page: http://www.nitrc.org/projects/fcon_1000/ http://www.nitrc.org/projects/fsl/ This fits the use case you describe and that of modules that would be a part of a Drupal installation or how djatoka can be a component of several different projects. Regarding the second question, I think of standards as a kind of technology. I've added standard to the list of enumerations at http://wiki.code4lib.org/index.php/Registry_E-R_Diagram Peter On Aug 3, 2011, at 7:06 PM, stuart yeates wrote: Two points: (1) The model seems appears not to capture Project A builds on Project B This will make the model less-than-optimal for comparing (for example) an open source Project A with an propriety Project B when B is a fork of A.

However, we're all ears for any suggestions you might have. I've been dealing with related issues for a few years, and if you have the file locally, it's generally not too difficult to have a CGI or similar that you can call that will do some sort of transformation on the fly. Unfortunately, what we've run into is that in some cases, in part because it tends to be used by people with slow connections, and for very large files, they'll keep restarting to the process, and because it's a generated on-the-fly, the webserver can't just pick up where it left off, so has to re-start the process. The alternative is to write it out to disk, and then let the webserver handle it as a normal file. Depending on how many of these you're dealing with, you may have to have something manage the scratch space and remove the generated files that haven't been viewed in some time. What I've been hoping to do is: 1. Assign URLs to all of the processed forms, of the format: http://server/processing/ID (where 'ID' includes some hashing in it, so it's not 10mil files in a directory) 2. Write a 404 handler for each processing type, so that should a file not exist in that directory, it will: (a) verify that the ID is valid, otherwise, return a 404. (b) check to see if the ID's being processed, otherwise, kick off a process for the file to be generated (c) return a 503 status. Unfortunately, my initial testing (years ago) suggested that no clients at the time properly handled 503 requests (effectively, try back in (x) minutes, and you give 'em a time) The alternative is to just basically sleep for a period of time, and then return the file once it's been generated ... but for ones that take some time (some of my processing might take hours, as the files that it needs as input are stored near-line, and we're at the mercy of a tape robot) ... You might also be able to sleep and then use one of the various 30x status codes, but I don't know what a client might do if you returned the same URL. (they might abort, to prevent looping) -Joe
