29 Jun '06

Dear mailing list subscriber, The Taxonomic Databases Working Group (TDWG, http://www.tdwg.org/) with support from the Gordon and Betty Moore Foundation has just held the second of two workshops to address the need for a system of globally unique identifiers (GUID) for use in biodiversity informatics. The report describing the outcomes of the meeting and the plans for deployment of LSIDs in our community is available at: http://www.tdwg.gbif.org/fileadmin/subgroups/tip/GUID2Report.pdf (PDF) http://wiki.gbif.org/guidwiki/wikka.php?wakka=GUID2Report (web page) We are encouraging feedback on the report and particularly the deployment strategy. Please send your comments to the TDWG-GUID mailing list at tdwg-guid(a)mailman.nhm.ku.edu, or add them to the TDWG-GUID wiki at http://wiki.gbif.org/guidwiki/wikka.php?wakka=GUID2ReportComments.

[Tdwg-guid] Paper
by Lee Belbin 28 Jun '06

28 Jun '06

Dear all Rod Page has just published an excellent paper "Taxonomic names, metadata, and the Semantic Web" http://jbi.nhm.ku.edu/index.php/jbi This paper spurred me to ask Ricardo to start setting up a list of LSID-related resources on the new TDWG web site. If you are aware of any, please send the link to Ricardo and we will keep you posted on developments.

It can be a problem but I'm not sure if there is a simple solution ... and how different is the LSID crawler scenario from an http://www.ipni.org/ipni/plantsearch?id= 1,2,3,4,5 ... 9999999 scenario?

As discussed at the meeting, we're thinking of providing a complete download of all IPNI LSIDs plus a label (name and author, probably) which will be available as an annually produced download Most people will play nice and just resolve one or two LSIDs as required, but by providing a complete list, we're making it very easy for someone to write a crawler that hits every LSID in turn and basically brings our server to its knees Anybody know of a good way of enforcing more polite behaviour?

[Tdwg-guid] Interest in versions - evidence from IPNI logs
by Sally Hinchcliffe 20 Jun '06

20 Jun '06

Hi all, As promised I've had a look at the ipni logs to see whether people are interested in particular versions of records or not. At the moment, the logs don't record that information directly, but I can see whether a user has clicked on the link to see the history of a record (a pre-requisite for clicking on an older version). I eliminated obvious crawlers and looked at just one server's queries for the week of 4th - 10th June, comparing the number of drill downs (into an individual record) with the number of history requests. Basically there were just under 5000 drill downs, of which 570 (10%) were followed by history requests, which was a slightly higher percentage than I was expecting. Some of these may simply be idle clickers looking out of curiosity, of course, but it does suggest that while most people aren't interested in versions, there is a significant minority who may have a need/interest/desire to see specific versions of records.

The LSID framework has provision for basic security (HTTP credentials), so this could be used for identifying end users and controlling the degree of their activity. Kevin >>> Roger Hyam <roger(a)tdwg.org> 19/06/2006 9:30 p.m. >>> I think the only way to throttle in these situations is to have some notion of who the client is and the only way to do that is to have some kind of token exchange over HTTP saying who they are. Basically you have to have some kind of client registration system or you can never distinguish between a call from a new client and a repeat call. The use of IP address is a pain because so many people are now behind some kind of NAT gateway. How about this for a plan: You could give a degraded services to people who don't pass a token (a 5 second delay perhaps) and offer a quicker service to registered users who pass a token (but then perhaps limit the number of calls they make). This would mean you could offer a universal service even to those with naive client software but a better service to those who play nicely. You could also get better stats on who is using the service. So there are ways that this could be done. I expect people will come up with a host of different ways. It is outside LSIDs though. Roger Sally Hinchcliffe wrote: It's not an LSID issue per se, but LSIDs will make it harder to slow searches down. For instance, Google restricts use of its spell checker to 1000 a day by use of a key which is passed in with each request. Obviously this can't be done with LSIDs as then they wouldn't be the same for each user.The other reason why it's relevant to LSIDs is simply that providing a list of all relevant IPNI LSIDs (not necessary to the LSID implementation but a nice to have for caching / lookups for other systems using our LSIDs) also makes life easier for the datascrapers to operateAlso I thought ... here's a list full of clever people perhaps they will have some suggestions Sally Is this an LSID issue? LSIDs essential provide a binding service between an name and one or more web services (we default to HTTP GET bindings). It isn't really up to the LSID authority to administer any policies regarding the web service but simply to point at it. It is up to the web service to do things like throttling, authentication and authorization.Imagine, for example, that the different services had different policies. It may be reasonable not to restrict the getMetadata() calls but to restrict the getData() calls.The use of LSIDs does not create any new problems that weren't there with web page scraping - or scraping of any other web service.Just my thoughts...RogerRicardo Scachetti Pereira wrote: Sally, You raised a really important issue that we had not really addressed at the meeting. Thanks for that. I would say that we should not constrain the resolution of LSIDs if we expect our LSID infrastructure to work. LSIDs will be the basis of our architecture so we better have good support for that. However, that is sure a limiting factor. Also server efficiency will likely vary quite a lot, depending on underlying system optimizations and all. So I think that the solution for this problem is in caching LSID responses on the server LSID stack. Basically, after resolving an LSID once, your server should be able to resolve it again and again really quickly, until something on the metadata that is related to that id changes. I haven't looked at this aspect of the LSID software stack, but maybe others can say something about it. In any case I'll do some research on it and get back to you. Again, thanks for bringing it up.

right behind Sally on this one. for there is a potential bigger problem here than just the unwanted attention of data scrapers - I prefer harvesters - like army ants ... ;-) ... because the effect of harvesting could be the same. All Species did it to Index Fungorum, if they had 'cornered the market', serving their rapidy past it's sell by date harvest (and apologetic acknowledgement of source) it could kill Index Fungorum and then where would we all be? Picking up the pieces and trying to fill in the gap between the death of IF and the birth of it's replacement ...

Isn't this rather the point -- we WANT to make it easy :-) But, I do realise that providers may run into a problem of being overwhelmed by requests (though, wouldn't that be nice -- people actually want your data). The NCBI throttles by asking people not to hammer the service, and some people leave around half a sec between requests to avoid being blocked. Connotea is thinking of "making the trigger be >10 requests within the last 15 seconds; requests arriving faster than that will be give a 503 response with a Retry-After header.", if that makes any sense. You could also provide a service for data scrapers where they can get an RDF dump of the IPNI names, rather than have to scrape them.

Paul -----Original Message----- From: tdwg-guid-bounces(a)mailman.nhm.ku.edu [mailto:tdwg-guid-bounces@mailman.nhm.ku.edu]On Behalf Of Roderic Page Sent: 19 June 2006 08:06 To: Kevin Richards Cc: tdwg-guid(a)mailman.nhm.ku.edu Subject: Re: [Tdwg-guid] Simple LSID resolver [ Scanned for viruses ] Ricardo notes that I've duplicated what Biopathways.org already provides (albeit with the use longer URLs). However, there are a couple of reasons for persisting in this. Firstly, I like short URLs. Secondly, I find having another implementation (and one that I can play with) to be useful. For example, Biopathways.org caches the metadata, so the links given by Ricardo work. I don't cache the metadata, and hence discover that the IndexFungorum LSID authority seems broken. The LSID resolves to host lsid.indexfungorum.org:8080, but if I ping lsid.indexfungorum.org I get nothing back, and my LSID resolver eventually fails with HTTP 504. What I think would be nice is to return metadata with a XSLT style sheet, so that the browser displays nice HTML, but view-source displays XML (which is also what a script would get), so that it supports both people and machines. For an example of this, see the handle demo for a paper on ants (http://hdl.handle.net/2254/20791) and view the source.

Re: [Tdwg-guid] Simple LSID resolver
by Roderic Page 19 Jun '06

19 Jun '06

Ricardo notes that I've duplicated what Biopathways.org already provides (albeit with the use longer URLs). However, there are a couple of reasons for persisting in this. Firstly, I like short URLs. Secondly, I find having another implementation (and one that I can play with) to be useful. For example, Biopathways.org caches the metadata, so the links given by Ricardo work. I don't cache the metadata, and hence discover that the IndexFungorum LSID authority seems broken. The LSID resolves to host lsid.indexfungorum.org:8080, but if I ping lsid.indexfungorum.org I get nothing back, and my LSID resolver eventually fails with HTTP 504. What I think would be nice is to return metadata with a XSLT style sheet, so that the browser displays nice HTML, but view-source displays XML (which is also what a script would get), so that it supports both people and machines. For an example of this, see the handle demo for a paper on ants (http://hdl.handle.net/2254/20791) and view the source. Lastly, I need a LSID client for my ant stuff, so developing the resolver helps me debug this code.
