Alpha release of the LAARC Search API is live

Archaeology, LAARC catalogue, Websites No Comments
The LAARC Search API is the beginning of upgrading and remodelling the original LAARC Catalogue web site. The LAARC Search API allows you to build your own specific search queries, and results will be returned in xml format. In addition, you will still be able to use the ‘Simple Search’ and ‘Advanced Search’ features of the existing LAARC Online Catalogue to search for data.At the end of the first phase we released a prototype of the LAARC Data Service. Apart form the API documentation, currently there is not much visual effect. The last two months were spent on re-writing the application code behind the GUI in order to open possibilities for the extension of the search functionality and for the new feature reach LAARC Catalogue web GUI.Many thanks to those who responded to our September’09 survey. Your comments gave us an impetus for planning our work and prioritising tasks. We also drew inspirations from existing museum and archaeology data providers such as ADS and Brooklyn Museum.If you’d like to check it out, the documentation pages for LAARC Search API are here.

Your evaluation feedback is very important to us. And, if you come across any bugs, do send us an email or leave a comment on this blog. Please, include the search url that caused the error or a sequence of steps that resulted in error.

Our vision for the LAARC on-line catalogue

Archaeology, LAARC catalogue, Websites No Comments

First of all, thank you very much for responding to the survey call

It is hard to overestimate the importance of what the users of LAARC web site really think. On a personal note, I was thrilled to learn that LAARC catalogue users exist! This means that the work that has been put in this web resource and will be put into it, is not attested to by some stillborn enterprise.

Summarizing your comments several interesting points have been raised

  • provide more kinds of filtered searches, e.g. “Roman pottery filtered by presence of a digital archive”
  • provide more kinds of filtered searches, e.g. “Roman pottery filtered by presence of a digital archive”
  • make more data on site archives available on-line (in addition to downloadable zipped archive bundles)
  • extend mapping and plotting of geographical data about sites
  • semantic search, e.g. ‘monastery’ or ‘latrine’ rather then ‘THE07′

It would be good to collect more use cases on these points, e.g. examples of other possible filtered searches, examples of archive data that could be brought on-line etc. Perhaps, you could point us to the links to other web resources containing desirable features that could also be implemented within LAARC catalogue?

A few comments about the current state of LAARC on-line catalogue

The map images to accompany site records returned to the live site in early August, and data updates were fixed back in July. New data was pumped onto the live site weekly up until 3 weeks ago when the web server was brought down by various attacks. Although the server is now running again some problems remain and we cannot yet perform data uploads, so there have been no updates to the data visible on the web site since then. However, those of you who visit Mortimer Wheeler House have access to the MoL internal version of the LAARC web application (no maps though).

LAARC staff work very hard to prepare digital archives, the web team makes them available to the web users but is not involved in the actual preparation of the digital archives for distribution.

Our vision for LAARC catalogue

Our ultimate ambition is to make LAARC catalogue a kind of data aggregator that is able to mash up data from the Museum’s Mimsy XG collections database with other information resources, and at the same time expose LAARC data in the formats (mostly xml, but also plain text, csv and other formats) that will allow other web services use it and mash it up with their resources. That is, to integrate LAARC catalogue data with the wider cultural information grid.

Of course, we are well aware that even partially achieving these goals means a good year’s worth of work, and given our very limited web development resources may be even longer. The prototype that lays out the architecture should be ready in November and will be linked to from the current LAARC on-line catalogue. There won’t be much visual effect as most of the effort at this stage has gone into engineering the invisible parts of the software that lay the foundations for the diverse presentation formats. And as with all software development the first release (a so called “alpha” release) will be intended for testing bugs until the next version comes out, which will have more functionality and more features. And so it will go in an iterative way (we hope).

The current LAARC catalogue site will remain available online, but no more new features will be put into the existing site. This is because the technology it uses limits its extensibility. Instead the development effort will focus on the new version of LAARC catalogue for which we are in the process of designing a flexible and extendable architecture.

There is also a risk that LAARC catalogue development may be put on hold temporarily as the need for other development will shift the priorities. Nevertheless, we are determined to continue doing work on LAARC catalogue even though the progress may not be as speedy as we would like it to be.
We also think that this blog can be an effective means for updating the users on the progress of the project development, so watch this space if you are interested. You can even add it as an RSS feed to your RSS reader.
And naturally, it will be fantastic if we could engage you in a continuing dialogue in order to build a bank of ideas of what LAARC catalogue should be.

Infuse LAARC catalogue with your inspirations

Archaeology, LAARC catalogue, Websites 7 Comments

You may be aware that Museum of London holds a catalogue of summary information on over 7500 sites and projects that have taken place in Greater London over the past 100 years!

This information is managed by the Museums’ London Archaeological Archive and Research Centre (LAARC). Just in case, you don’t know where it is, the catalogue is part of the Museums website and can be found at www.museumoflondon.org.uk/laarc/catalogue.

The web site is aimed at delivering the LAARC’s vast and invaluable data resources on London Archaeology to researchers and to the public at large.It was launched in 2000 and as we are fast approaching 2010 we believe after nearly a decade, it could do with some improvement. Ideas have been brewing for some time on how to infuse life into the LAARC online catalogue. Our vision for redevelopment of LAARC web resource is greatly inspired by the new generation Web 2.0 and cloud computing technologies for data mining and information exchange. However, ultimately our goal is to deliver to the users of LAARC a web tool that is beneficial for your investigative zest and that would help foster your interest in London archaeology.Your views are important to us and will help us greatly to move the project forward in the right direction.

We will appreciate very much if you let us know:

  • Is the LAARC online catalogue a useful data resource?
  • What can we do to make it more useful and interesting?
  • What do you like/dislike about the current web site?
  • What content, data, display, navigation or features are the most desirable to you?
  • What would make the LAARC web resource more attractive to you?

I very much look forward to hearing from you. Please post your answers or comments in the comments box below, or email us at webmanager@museumoflondon.org.uk.

Many thanks,

Julia Fernee, Museum of London Web Development
