Web of Science: REST or SOAP?

REST or SOAP Which style of Service is “best” for building the Web of Science? Duncan Hull Web Services Workshop 2007-09-20

Looks like we’ll be developing some WS-* ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

WS-* are interesting because they transform the web into… ,[object Object],one open-ended, vast, decentralised computer

Creating a bioinformatics nation? ,[object Object],--Lincoln Stein, Cold Spring Harbor Laboratory Nature 2002, 417(6885):119-20 http://view.ncbi.nlm.nih.gov/pubmed/12000935 e.g. “jimome” browser at http://jimwatsonsequence.cshl.edu/

[object Object],--Alberto Labarga et al in Nucleic Acids Research European Bioinformatics Institute (EBI), see http://www.cs.man.ac.uk/~hulld/q2007-06-28.html

[object Object],--Werner Vogels, Chief Technology Officer (CTO) Amazon.com, interviewed in ACM Queue, 2006 see, http://www.cs.man.ac.uk/~hulld/q2006-09-27.html

WS-heaven or WS-hell? Users / clients Internet or Web (Interweb)?! http://en.wikipedia.org/wiki/Interweb Service providers: INPUT OUTPUT etc… workflow

SOAP and WSDL walkthrough Registry WSDL / UDDI Search / Browse SOAP (xml) HTTP INPUT / OUTPUT http://www.w3.org/TR/soap/ http://www.w3.org/TR/wsdl/ Ugly, heavyweight and complicated, seems like overkill? “ layers of complexity that aren’t needed”?

No matter how hard I try, I still think the WS-* stack is bloated, opaque, and insanely complex. I think it's going to be hard to understand, hard to implement, hard to interoperate, and hard to secure. --Tim Bray, Director of Web technology at Sun Microsystems Inc., “Loyal opposition to Web Services” (2004) http://www.cs.man.ac.uk/~hulld/q2004-11-02.html

Web service goodness The problem is most of today's “web services” have nothing to do with the Web.... Today's “web service” architectures reinvent or ignore every feature that makes the Web successful. --Leonard Richardson & Sam Ruby (IBM) “ RESTful Web Services ” (2007) book, see http://www.cs.man.ac.uk/~hulld/q2007-06-30.html

H.T.T.P. is just C.R.U.D…Create, Read, Update, Delete H.T.T.P. is K.I.S.S. too ( K eep I t S imple S tupid) DELETE (delete an existing resource) D ELETE PUT (modify or overwrite an existing resource) U PDATE GET (Retrieve a representation of a resource) R EAD POST (create a new resource) C REATE HTTP request method CRUD

REST example: EBI services OR OR etc.

REST criticism ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

Conclusions 1: Gartner’s Hype cycle ,[object Object],Web services are now past the peak of inflated expectations, through the trough of disillusionment, on the way toward mainstream adoption. 2000 2002 2004 2006 2008 You are here (probably) SOAP WSDL

Conclusions 2: Who can you trust? ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Don’t trust ANYONE about Web Services (including me!)
