Relying on Web Services

Recently we have had two examples of trusted resources being off line for an extended time. A few weeks ago the GPO PURL server was down for several days. This meant that thousands of links in library catalogs around the globe were broken.

Now the NASA Technical Reports Server is down. It went down about a week and a half ago. No word on when it will return. It went down Monday, on Wednesday this notice appeared
The NASA Technical Reports Server is currently unavailable as of September 24, 2009, due to unforeseen but required data maintenance. We apologize for the incovenience [sic]. NASA hopes to make this database available in approximately 1 week.
This affects fewer libraries but in my catalog hundreds of links to the full-text stored at the server are broken.

It seems we have put too much reliance in trusted sites (NASA, GPO). What does this mean for mash-ups? For the Web in general? If we can't trust NASA or the GPO to keep vital services up, who can we trust? Just musing.

Oct. 6 Update: The NTRS Server is still down.

WorldCat Mashathon Seattle

News from OCLC, the next WorldCat Mashathon Seattle.
Join fellow developers for the next two-day WorldCat Mashathon. Sponsored by the OCLC Developer Network and the University of Washington libraries, this WorldCat Mashathon will be held Thursday and Friday, November 5-6 at Odegaard Undergraduate Library at the University of Washington, Seattle.

The Seattle Mashathon will follow the same format as previous events in Amsterdam and New York. Participants will spend the two days brainstorming and coding mash-ups with local systems and other Web services to take advantage of all that WorldCat, the world's largest and most comprehensive bibliographic database, has to offer. Developers from the library community and beyond are encouraged to attend.

WorldCat includes materials from libraries around the world, including images, video games, movies, articles, books, maps and more.

Why attend the WorldCat Mashathon?

  • Brainstorm potential apps for the WorldCat Search API, our bibliographic grouping services and other OCLC Web services.
  • Get a preview of the new WorldCat Basic API.
  • Gain development access to 1.4 billion items from more than 10,000 libraries worldwide.
  • Integrate these resources with many others to create innovative new services.
  • Meet fellow developers across the information industry.
  • Share your creative vision and be a part of the next wave of online library development.
Roy Tennant of OCLC Research and longtime Code4Lib participant will kick off the session. OCLC staff will also be available for questions and breakout facilitation. Ideas, outcomes and code from the Mashathon, together with a participants list, will be shared during and after the event for others to download and build on.

Learn more and register now for the Mashathon.

LC is finally changing the subject heading Cookery to Cooking in most cases. Long overdue.

Library Mashups

I just received my copy of Nicole C. Engard's Library Mashups: Exploring New Ways to Deliver Library Data. Thank you Nicole for editing this book. I've only have time to skim it and read one paper but it looks like a winner. Can't wait to read more.

The article I read was on making your library's data accessible by Ross Singer. YES. Microformats, RDFa and eRDF, linked data, COinS, unAPI and other POSH (plain old semantic HTML) are all things I consider important.

440/490/8XX Problem

Over on Bibliographic Wilderness there is an interesting discussion about display and indexing of series information. Shows a true weakness of MARC.
