Re: [Dspace-tech] Persistent identifiers in DSpace -- thoughts please
About the URLs to access objects, it's really a matter for each DSpace UI webapp to implement, isn't it? I think it's important to include a pathname component to introduce the encoded(*) object-URI, however, just to protect against namespace collisions -- e.g. what if the UI design had one of its own URLs starting with "doi"? How about the word "resource" to introduce the URI, since it is, after all, a reference to a resource -- the "R" in URI. It'd be: /resource/ e.g. http://dspace.me.ac.uk/resource/hdl/1234/56 This follows the proposal to encode the URI by tearing off the scheme and putting it in a separate pathname element to avoid issues over quoting the ":". Note that I propose using the actual scheme label in the URL rather than a user-friendly label, e.g. "hdl" rather than "handle". Re special characters and quoting: I agree with James' original point that the HTTP URL spec has quoting rules for just this reason, but from a practical point of view, the client and server implementations have a lot of bugs in this area. That's what I discovered implementing WebDAV for the LNI: it wasn't worth trying to encode a slash (/) in a URL, e.g. within a Handle, because it would just get stomped on differently by the different clients. Better to let it get used literally as a path element separator and make the servlet clever enough to figure it out. Also, construct the servlet's URL so the whole path after a certain point is part of the object URI, e.g. the Handle. Also note that the transformation from object URI to the actionable URL is reversible -- we can pull the URI's scheme and path right out of the URL and put it back together unambiguously. I think it's essential to have one unambiguous transformation for all URIs. > > 3) Including special characters in the URL string doesn't seem like a > > good idea.

[Dspace-tech] Import : Fatal error UTF-1
Hi I am using Foxpro 6.0 to write the .xml files for importing. The importer (Dspace 1.3.2 on FC 3.0) gives a fatal error for special characters (e.g ° ð ö alpha , beta etc. ) in dublin_core file I have tried file converters from ANSI to UTF-8 but no use the importer fumbles. Is there any other way / utility to overcome this problem. Tushar Sangamnerkar TIRC Pune - You snooze, you lose. Get messages ASAP with AutoCheck in the all-new Yahoo!

The smoke test has a method doPut() which ought to be a viable example. Is that what you're using? It takes the Handle of a collection which you have write access too. The Handle should be a string like "123456789/241"; the sample code uses the Lookup operation to get its LNI resource URI. Check that the "packager" value names a PackgeIngester plugin configured in dspace.cfg. It may help to crank up the log level to "DEBUG" and look at the server logs. -- Larry - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

Re: [Dspace-tech] Granularity of Authentication
Hi Jesús I think this approach works for us because the majority of items are in the open access category, if you have a real mixed bag then perhaps its is not so easy to implement and not the answer for you. The private items are only viewable by the collection-admin (the main one) and/or the dspace-admin account, we either restrict the whole record or the bitstreams. If you wanted to allow other users to view the item this would get very messy and be hard to administer. Essentially the permissions occur at the item level and bitstream. Hope this make its clear. 1. Item is input within the normal submmission environment 2. Collection admin approves for entry 3. Permissions are applied by editing the record using the authorisations view I have seen other examples of theses with various levels of authentication better dealt with using the Tapir addon Cheers Leonie Hayes Project Manager Institutional Repositories Aotearoa University of Auckland Library New Zealand www.ira.auckland.ac.nz -Original Message- From: Jesus Martin [mailto:[EMAIL PROTECTED] Sent: Monday, 28 May 2007 10:12 p.m. To: Leonie Hayes Cc: dspace-tech@lists.sourceforge.net Subject: Re: [Dspace-tech] Granularity of Authentication Hi Leonie, after I read your message about granularity of authentication I have few questions: - how do you give permissions to public or private items in the same collection? - Do you use the dspace-admin account or there is another method whithout the dspace-admin account and without changing the permissions of the collection every time that a new item is inserted?

[Dspace-tech] Upgrading from mod_webapp to mod_jk
Hi... I have been running Apache 1.3 with mod_webapp to tomcat-4.0.6 (dspace 1.3.2) I am planning on upgrading to Apache 2.2 with mod_jk to tomcat 5.0.28 When I tried to cutover, I found that everything worked fine EXCEPT for my URLs Under the old configuration, the home URL was http://dspace.library.cornell.edu Under the new configuration, the home URL became http://dspace.library.cornell.edu/dspace All of the URLS needed to have the extra path of "/dspace/" added to work. For instance http://dspace.library.cornell.edu/community-list worked under the old configuration. Under the new configuration, the URL would only work as http://dspace.library.cornell.edu/dspace/community-list I suspect that something in my mod_jk configuration needs to changed. I currently have: JkMount /dspace/* ajp13 JkMount /dspace-oai/* ajp13 I tried to change things to: JkMount /* ajp13 as suggested in the WIKI but that caused me other problems (I have other virtual servers running on the server). Does anyone have any suggestion as to what I can do to drop the "/dspace/" so that my links will be like they were when I used mod_webapp? *** George Kozak Coordinator Web Development and Management Digital Media Group 501 Olin Library Cornell University 607-255-8924 *** [EMAIL PROTECTED] - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

You should be able to restore this dump using something like 'pg_restore -d dspace /dspace/backup'. 'man pg_restore' and read carefully to see what other options you may need. In particular read about how pg_restore handles ownership of database objects. Please take my PG suggestions only with a grain of salt. I don't do this stuff often enough to really learn it.

Re: [Dspace-tech] Problem with Data Provider Validation
Hi Keith, Seems to be some date problem as http://dspace.udel.edu:8080/dspace-oai/request?verb=ListIdentifiers&from=2000-05-02&until=2007-05-02&metadataPrefix=oai_dc adding the optional arguments for "from" and "until" works. So there must be something with the implicit from earlist date until today for this request if no date range is given.

If have objects replicated from some other dspace via some replication scheme, the local identifiers (uid) are always different for those replicated items, any global identifiers (purl, handle, doi, lsid,...) do stay the same. The current PLEDGE (AIP) work does support a unique uri scheme for DSpace objects that should meet this requirement. See details here: http://wiki.dspace.org/index.php/ObjectUri http://wiki.dspace.org/index.php/HistorySystemPrototype http://wiki.dspace.org/index.php/AipPrototype Some of these uri get "horrid" as you put it with lots of escaped chars and uri encoding required, it would be good to discuss a syntax that does not require heavy amounts of uri encoding (which is an other separate topic in this thread). 2.) All global identifiers may provide their own resolution mechanism, and these are "diverse", its probably best DSpace should not try to provide a common "resolution service" for global identifiers. Each service needs/may to provide its own via the AddOn mechanism. 3.) DSpace needs to provide a common "registration service" or API which can be implemented in AddOn's for registering new global identifiers in various services, this mechanism may be "stackable" and support the registration of various global identifiers according to the naming scheme of that naming service (handle, purl, doi, oclc, etc.) So, I think while UUID's would be sufficient, they are not necessary. The system would be robust with just unique identifiers per site. -Mark ~ Mark R.

If we don't use the canonical form of persistent identifiers for this, then we'll need to use another identifier that is unique across the site (presumably, something based on the database id of the object).

But there is strict and there is strict... and it isn't entirely clear that the handle should be treated as a complete unit rather than the separation of prefix and suffix - globally, that's how they need to be referred to, but then we're discussing local urls here ;-) Yes an unescaped slash isn't going to do anything harmful. An unescaped colon in the middle of the url could easily trigger url parsing bugs and security problems. G This email has been scanned by Postini.

Re: [Dspace-tech] Persistent identifiers in DSpace -- thoughtsplease
Hey Folks, PI resolvers come in all shapes and sizes, What all your talking about implementing is proxy/resolution. I would highly recommend NOT conflating the PI resolution mechanism (and why do we even have to have one) with the url path with which a Community, Collection, Item or Bitstream is referenced under in DSpace. What this means is that you do not have a url on with you have to worry about the identifier being properly escaped. You also only have to be concerned with resolving one path to the Item for "any" PI system. I.E. hdl:1234/5 --> http://dspace.me.ac.uk/item/ABCD and also doi:6789/0 --> http://dspace.me.ac.uk/item/ABCD Don't conflate local and global identification.

Well if we're going to be strict, we should escape the value of the handle 1234/56 as 1234%2F56. Since DSpace already breaks this rule, I didn't deem including a colon as such a great crime ;) Of course, it would be better if we could use an identifier scheme that didn't require escaped characters, but most will at least have a "/" to separate prefix from suffix. If we're going to be strict, I think I'd favour the following form: http://dspace.me.ac.uk/uri/hdl%3A1234%2F56 or maybe http://dspace.me.ac.uk/uri/hdl/1234%2F56 Jim -- James Rutherford | Hewlett-Packard Limited registered Office: Research Engineer | Cain Road, HP Labs | Bracknell, Bristol, UK | Berks +44 117 312 7066 | RG12 1HN.

The colon is a reserved character, and in this example would have to be encoded to be strictly valid according to the specifications - which would then mean it isn't the canonical form. Not encoding the colon will have the potential to cause problems with proxies, firewalls, etc. G This email has been scanned by Postini.

Whilst it is necessary to identify the persistent id scheme, that doesn't mean that using a colon as part of the identifier is necessary or desirable. Colons - or other 'unusual' characters - will end up causing problems. In fact, I don't even see that there is a reason to include 'uri' in the url. Why not just support the existing: http://dspace.me.ac.uk/handle/1234/56 for handles, and: http://dspace.me.ac.uk/doi/7890/12 for DOIs, etc.?

Something to note is that I don't anticipate objects normally having more than one identifier. While the prototype allows this, it will still be the case that objects are only assigned one identifier (according to configuration -- the details of which are still undecided) but now we are able to associate multiople identifiers to objects (the stack is there to define what we understand), and resolve them all to the correct place. > 3) Including special characters in the URL string doesn't seem like a > good idea.

Why not just > leave the URL alone or change /handle to something like /uri, /id, or > /pid? Why encode the PI system into the URI? As I mention on the wiki, my current idea is to have URLs of the form: http://dspace.me.ac.uk/uri/hdl:1234/56 which will resolve to the object with Handle 1234/56, etc. If the object also has a DOI with value 7890/12 then the following URL would point to the object as well: http://dspace.me.ac.uk/uri/doi:7890/12 It is necessary to include the "hdl:" and "doi:" parts so we can distinguish between different persistent identifier mechanisms. The values allowed for the persistent identifier are dependent on the mechanism we are dealing with, and as far as possible this will be kept simple. > As far as having a default PI system out of the box for Dspace, I would > recommend using a local identifier schema which used the existing URLs. > Include the Handle PI system in the release as a configurable option, > but not turned on by default. This would remove the fake handle being > assigned to all objects and clean up the default URLs out of the box. I've already experimented with a "null" identifier that can be used to resolve to objects locally. For example, in my prototype, the following url would resolve to the Item with internal id 4: http://dspace.me.ac.uk/uri/dsi:2/4 I'm still not convinced that this is a good idea, but it seems useful and it makes accessing individual bitstreams a little more predictable and consistent with the other objects. cheers, Jim -- James Rutherford | Hewlett-Packard Limited registered Office: Research Engineer | Cain Road, HP Labs | Bracknell, Bristol, UK | Berks +44 117 312 7066 | RG12 1HN.

[Dspace-tech] Postgres optimizations
Im hoping to get some hints for postgres performance optimization. Our DSpace (1.4.1) has started to run really slow after the number of items exceeded 40 000 (mainly metadata, few full texts only). I tried increasing work_memory and max_fsm_pages in postgres.conf but with little help. Im also running regular vacuum and reindex for the db. Any help would be appreaciated, -Mika - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML. No limits. Just data.
