Abstract

In my talk, I will discuss work that my colleagues (Tom Schirmer and Annie Yeh) and I have been doing at the Interactive University towards prototyping highly resuable bibliographic and image collections.

On the bibliographic side, I will demonstrate

• use and reuse of bibliographic references from CDL infrastructure: Melvyl, metasearch, OAC, including the production and use of RSS feeds within Scholar's Box and outside of Scholar's Box, the implementation of the Metalib X-server API in Scholar's Box and the attendant issues of bibliographic metadata interoperability (MARCXML, OpenURLs, LOM)

• interoperability demos for moving resources into (and out of?) Sakai 1.5 via RSS

• transporting references via more portable OpenURLs. See http://www.openly.com/openurlref/latent.html for example

• some first interactions with a range of social bookmarking/bibliographic systems: del.icio.us, unalog, CiteULike, connotea.org

On the image collection side, I will present

• our work with flickr as a prototypical personal photo repository, its API, and mixing flickr pictures with archival content (such as from CDL) -- and taxonomies vs folksonomies -- and drawing content from flickr into my wiki programmatically (e.g., http://raymondyee.net/wiki/BerkeleyBowl and http://raymondyee.net/wiki/CzeslawMilosz)

• some preliminary work on mapping and images: eocoding of images on the cheap and mixing it with google maps (and using google maps and the Yahoo APIs to pull together to put pictures on a map) -- and lowering the barrier to entry for GIS

Time permitting, I will also present some first observations of Chandler 0.5 and its repository architecture and object model. My hope is that Chandler 0.5 will provide a good architecture of the managment of collections of diverse object types.

Bibliographic Collections

Melvyl

• It might be good to remind folks that it is possible to get XML out of Melvyl: see notes at MelvylSystem

• Example of the XML in my wiki: Milosz's Second Space

  But what can one do with the XML?

• RSS 2.0 functionality in ScholarsBox (e.g., /AyersRssExample -- see RSS output)

• RSS 2.0 out of Melvyl: RSS 2.0 search form

• nice to validate the RSS. e.g., Melvyl RSS 2.0 for 'flower' with feedvalidator

• RSS 2.0 for use in A9's OpenSearch. Try prototyping the OpenSearch™ Description Document URL -- but please don't submit.

• RSS 2.0 for moving resources into Sakai 1.5. I'll demonstrate it in my own trial account of bSpace: UCB Sakai Implementation: http://lms.media.berkeley.edu:8080/portal

(related to http://orweblog.oclc.org/archives/000645.html)

Possible future steps

• one-step to XML, instead of two-steps to get XML out of melvyl

• interesting idea: SRU interface to melvyl

Metasearch

• demo of the MetaLib system: /MiloszMetalibRssExample RSS 2.0. I added it to MyYahoo!

Latent OpenURLs

• problem: not everyone has an OpenURL resolver...and everyone's OpenURL resolver is different!

• old example: demo and explanation

• current proposal on the table: Latent OpenURLs in HTML

Metadata interop issues

• wrapping of BibUtils: cgi wrapper about BibUtils

Our XMLization of our collections

• What XML format to use?

social bookmarking

• See Social Bookmarking Tools (I): A General Review and Social Bookmarking Tools (II): A Case Study - Connotea

• systems to look at: my del.icio.us, connotea, and unalog

Chandler 0.5

• We have a Melvyl parcel for Chandler 0.5. (On my machine, I need to type D:\chandler\Chandler_win_debug_0_5_02\debug\bin\chandler --create -W

Image Collections

• I'll talk about what I've been doing with FlickrSystem

Mapping/GIS

• GoogleMapsHacking

• where I've been learning: Home : myGmaps: myGmaps enables you to create, save and host custom data files and display them with Google Maps.

• Housing: craigslist x google maps

flickr mapping

• a question I posed about how to map my flickr pictures

• 2195 Hearst restaurants with some of my flickr pictures

Demo of customized Google and Keyhole maps generated from the Yahoo API

• gmap written by my script static demo

• can play same trick with Keyhole XML. e.g., kml for bookstores around 94705
