Lonclass and RDF
Lonclass and RDF: "Lonclass and RDF
By DANBRI | Published: 2010-11-18
Lonclass is one of the BBC’s in-house classification systems – the “London classification”. I’ve had the privilege of investigating lonclass within the NoTube project. It’s not currently public, but much of what I say here is also applicable to the Universal Decimal Classification (UDC) system upon which it was based. UDC is also not fully public yet; I’ve made a case elsewhere that it should be, and I hope we’ll see that within my lifetime. UDC and Lonclass have a fascinating history and are rich cultural heritage artifacts in their own right, but I’m concerned here only with their role as the keys to many of our digital and real-world archives.
Why would we want to map Lonclass or UDC subject classification codes into RDF?"

The Nature of Connectedness on the Web » AI3:::Adaptive Information: "What does it mean to interoperate information on the Web? With linked data and other structured data now in abundance, why don’t we see more information effectively combined? Why express your information as linked data if no one is going to use it?
Interoperability comes down to the nature of things and how we describe those things or quite similar things from different sources. This was the major thrust of my recent keynote presentation to the Dublin Core annual conference. In that talk I described two aspects of the semantic “gap”:
One aspect is the need for vetted reference sources that provide the entities and concepts for aligning disparate content sources on the Web, and
A second aspect is the need for accurate mapping predicates that can represent the often approximate matches and overlaps of this heterogeneous content.
I’ll discuss the first “gap” in a later post. What we’ll discuss here is the fact that most relationships between putatively same things on the Web are rarely exact, and are most often approximate in nature."

LISTSERV 15.5 - NGC4LIB Archives: "The Variations/FRBR Project at Indiana University (http://vfrbr.info) has released version 1.1 of a set of XML Schemas designed for the representation of FRBR (http://www.ifla.org/en/publications/functional-requirements-for-bibliographic-records) data in XML. The 1.1 Schema release represents some significant improvements over our earlier 1.0 release, particularly in the handling of FRBR relationships. As before, the Variations/FRBR XML Schemas are defined at three 'levels': frbr, which embodies faithfully only those features defined by the FRBR and FRAD reports; efrbr, which adds additional features we hope will make the data format more 'useful'; and vfrbr, which both contracts and extends the FRBR and FRAD models to create a data representation optimized for the description of musical materials and we hope provides a model for other domain-specific applications of FRBR."
Querying the British National Bibliography
Querying the British National Bibliography
Following up on the earlier announcement that the British Library has made the British National Bibliography available under a public domain dedication, the JISC Open Bibliography project has worked to make this data more useable.
The data has been loaded into a Virtuoso store that is queriable through the SPARQL Endpoint and the URIs that we have assigned each record use the ORDF software to make them dereferencable, supporting perform content auto-negotiation as well as embedding RDFa in the HTML representation.
The data contains some 3 million individual records and some 173 million triples. Indexing the data was a very CPU intensive process taking approximately three days. Transforming and loading the source data took about five hours.
To get an idea of the shape of the data, let us consider a sample resource, http://bnb.bibliographica.org/entry/GB8102507 . Apart from linkage between the various representations, the description of the entity itself is as follows

Open Bibliographic Data Guide: "The advice is both general and specific. The guide seeks to clarify in general terms and also in the context of 17 specific Use Cases:
How to license the data
Legal issues to be considered
Potential costs and savings
Practical implications in terms of processes, effort and skills
Data formats and other technical options
These Use Cases cover things you might already do or plan to do as you develop your library service. The Guide provides the rationale and the potential ripple effects of doing those things based on Open Data."

inkdroid › iogdc ramblings: "There was a question about how to make Linked Data relevant to folks whose focus is Enterprise data. In my opinion Linked Data advocates over emphasize the importance of using RDF and SPARQL (standards), and converting all the data over without completely understanding how invasive these solutions are. Not enough is done to show enterprise data folks, who typically think in terms of relational databases, what they can do to put their lovingly crafted and hugged data on the web. Consider a primary key in a database: what does it identify, what relations does that thing have with other things? Why not use that key in constructing a URL for that thing, and link things together using the URLs? Then other people could use your URLs as well in their own data. I think the drumbeat to use SPARQL and triple stores often misses explaining this fundamental baby step that data owners could take. As Derek Willis said (on the 2nd day, when I’m writing this), people want to use your data, but not your database…people want to browse your data using their web browser. Assigning URLs to the important stuff in your databases is the first important step to make with Linked Data."

PDF/A: A Viable Addition to the Preservation Toolkit: "PDF/A, the archival version of the PDF file format, is an International Standards Organization (ISO) vetted, open source tool that can be added to the librarian's and archivist's preservation toolkit. This article describes the format itself, the lessons learned as the authors investigated the tools readily available for creating PDF/A files and the design of the pilot to test implementation of the use of the format in The Ohio State University's repository, the Knowledge Bank. Further, we identify issues in conversion of diverse original formats; strategies for time-saving batch conversion; and considerations in deciding whether to attempt full or partial compliance with the standard."
Trends in Large-Scale Subject Repositories
Trends in Large-Scale Subject Repositories: "Conclusion
This study illustrates that there are a number of trends among the ten largest subject repositories:
the most populated subject repositories were established before 2000, with the exception of PMC
most of the top ten repositories are inter- and multidisciplinary
the sciences and social sciences are predominant
the use of local software was more common for subject repositories until the launch of open source repository software in 1997
'articles,' or pre- or post-prints, is the only common content type
deposits are moderated
repositories discourage withdrawal of materials
submitters are responsible for copyright policies
most repositories are hosted by university libraries or departments"

The Strongest Link: Libraries and Linked Data
The Strongest Link: Libraries and Linked Data: "Abstract
Since 1999 the W3C has been working on a set of Semantic Web standards that have the potential to revolutionize web search. Also known as Linked Data, the Machine-Readable Web, the Web of Data, or Web 3.0, the Semantic Web relies on highly structured metadata that allow computers to understand the relationships between objects. Semantic web standards are complex, and difficult to conceptualize, but they offer solutions to many of the issues that plague libraries, including precise web search, authority control, classification, data portability, and disambiguation. This article will outline some of the benefits that linked data could have for libraries, will discuss some of the non-technical obstacles that we face in moving forward, and will finally offer suggestions for practical ways in which libraries can participate in the development of the semantic web."

Presentation of interest focusing on Research and Next-Gen Catalogues « The Cataloguing Librarian
Presentation of interest focusing on Research and Next-Gen Catalogues « The Cataloguing Librarian: "Amy Eklund gave a very good presentation on the shortage of research we have examining next generation catalogues, and areas that need to be explored.
Key points?
We should examine next generation catalogues because:
1. So far, a build it and they will come approach has been taken with these catalogues;
2. Discovery tool overlays, such as Encore and AquaBrowser, are not integrated with the catalogue, but sit on top, like an interface;
3. Next generation catalogue features are not based on large scale of evidence; and
4. Rich content contained in our bibliographic records is still not being used to its greatest potential."

Linked Data tools: Semantic Web for the masses / Lisa Goddard and Gillian Byrne
Semantic Web technologies have immense potential to transform the Internet into a distributed reasoning machine that will not only execute extremely precise searches, but will also have the ability to analyze the data it finds to create new knowledge. This paper examines the state of Semantic Web (also known as Linked Data) tools and infrastructure to determine whether semantic technologies are sufficiently mature for non–expert use, and to identify some of the obstacles to global Linked Data implementation.

inkdroid › routers, webcams and thermometers: "At the end of the day, it would be useful if the W3C could de-emphasize httpRange-14, simplify the Architecture of the World Wide Web (by removing the notion of Information Resources), and pave the cowpaths we already are seeing for Real World Objects on the Web. It would be great to have a W3C document that guided people on how to put URIs for things on the web, that fit with how people are already doing it, and made intuitive sense. We’re already used to things like our routers, cameras and thermometers being on the web, and my guess is we’re going to see much, much more of it in the coming years. I don’t think a move like this would invalidate documents like Cool URIs for the Semantic Web, or make the existing Linked Data that is out there somehow wrong. It would simply lower the bar for people who want to publish Linked Data, who don’t necessarily want to go through the process of using URIs to distinguish non-Information Resources from Information Resources.
If the W3C doesn’t have the stomach for it, I imagine we will see the IETF lead the way, or for innovation to happen elsewhere as with HTML5."

Nodalities � Blog Archive � LOD Around-the-Clock (LATC): "The challenge that all of these accidental technologists face is how to surface data and bring data together in meaningful ways. As Google’s chief economist Hal Varian has said, the scarce factor is no longer the data, which is essentially free and ubiquitous, but now the “scarce factor is the ability to understand that data and extract value from it.”
The emerging Web of Linked Data is the largest source of this data—multi-domain, real-world and real-time data—that currently exists. As data integration and information quality assessment increasingly depends on the availability of large amounts of real-world data, these new technologists are going to need to find ways to connect to the Linked Open Data (LOD) cloud."

For the first time, developers and users could query our database of over 1 million content items by using the common external identifiers of a MusicBrainz ID or an ISBN number. It is our first step into the world of ‘Linked Data’.
The Open Platform Content API was launched as a beta in 2009, and earlier this year was launched as a commercial product, allowing partners to re-use Guardian & Observer content in a variety of different ways. There is, for example, a Wordpress plugin that easily allows you to include Guardian content in your blog, and developers have built applications like a bespoke recipe search on top of the data. It is a unique proposition amongst news organisations on the web, and as well as the Content API itself, the Open Platform also includes publishing the source data behind Guardian journalism on the Data Store, and providing a search engine for Government datasets from around the world."
