pazpar2: New Features and Challenges
by dennis on 2012.03.30

It has been quiet on the pazpar2 front lately, but I will make amends with this blog post.

Lately I have been working on a Harvester that would harvest into a Local Unified Index (LUI). The LUI has been implemented with Solr.

This means we can implement Integrated Search, which is our name for doing both searching remote targets (meta-searching) and a Local Unified Index (LUI), aka Central Index.

New Features

With this we saw a need to move the faceting logic from our UI into the backend. The old UI would combine (anding) the user-entered search with the faceting value.

Code4lib 2012

Code4lib 2012, Seattle

I was the lucky winner of the Index Data lottery (no actual lottery took place) to go to Code4lib 2012. I was a (Code4lib) Newbie, so I didn't really know what to expect, but reading Jakub's blog about his experiences, it sounded like great fun.

It was also my first time in Seattle, so I did take some extra days on both ends to do some exploring. Arriving on Saturday to sunny and warm weather (15 degrees Celsius warmer than Copenhagen, nice!), Seattle did its best to welcome me.

What if it's about the People, Stupid?

Most of the science of Information Retrieval centers around being able to find and rank the right set of documents in response to a given query. We spend much time arguing about technical details like ranking algorithms and the benefits of indexing versus broadcast searching. Every Information Professional I know both deifies and fears Google because they get it right most of the time -- enough so that many people tend to assume that whatever pops to the top of a Google search MUST be right, because it's right there, in the result screen.

Index Data's DPLA submission
by sebastian on 2011.06.20

Index Data has posted a statement of interest to the DPLA (Digital Public Library of America) beta sprint. We are submitting this together with two academic partners.

The proposal in many ways reflects our broader thinking about information architectures and the flow of metadata between organizations, so we thought it would be useful to share it here. Fans of ID may notice that, yes, we are looking at Linked Data too.

Index Data’s Integrated Discovery Model
by sebastian on 2011.06.13

We are often asked about where we stand on the discussion of central indexing versus broadcast metasearching. Our standard answer: "You probably need some of both" always calls for further explanation. Some time ago, I wrote this up for a potential business partner. If it sounds a little like a marketing spiel... guilty as charged. I hope the content will still seem interesting to some folks thinking about these issues.

Code4lib 2011 Report -- Part2

Code4lib 2011 in Bloomington, IN -- Part2

Good things come to those who wait! Here's the Code4Lib 2011 Report Part 2. I toyed with the idea of postponing it indefinitely and have you checking impatiently the Index Data's blog RSS feed but Higher Powers persuaded me otherwise :).

So it took me a while to process all that happened during the conference and come up with a short summary.

On preferring open-source software
by mike on 2011.01.31

I spent most of last week up in Edinburgh, for the Open Edge conference on open-source software in libraries, attended mostly by academic librarians and their technical people. It was an interesting time, and I met a lot of interesting people. At the risk of overusing the word "interesting", it was also of interest to see how widespread the deployment of "next-generation OPACs" like VuFind and Blacklight has become.

Clustering Snippets With Carrot2
by jason on 2010.11.20

We've been investigating ways we might add result clustering to our metasearch tools. Here's a short introduction to the topic and to an open source platform for experimenting in this area.

SOLR support in ZOOM, Pazpar2, and MasterKey
by dennis on 2010.09.17

We have always held that the schism between broadcast metasearching and local indexing is rather goofy -- that in practice, you do whatever it takes to get the results in front of your user when and where he needs it, and the best solutions will allow for whatever approach is needed in the moment. Inspired by the increasing popularity of the SOLR/Lucene indexing server in the library world, we have just completed a project to add support for SOLR targets in the ZOOM API implementation in the YAZ library. So YAZ now supports Z39.50, SRU/SRW 1.x and the SOLR API.
