California Digital Library Announces New Release of the eXtensible Text
Framework (XTF)
 
Oakland, CA, May 12, 2008 - The California Digital Library (CDL) is pleased
to announce a new release of its search and display technology, the
eXtensible Text Framework (XTF) <http://www.cdlib.org/inside/projects/xtf/>
version 2.1 (http://www.cdlib.org/inside/projects/xtf/
).  XTF is an open source, highly flexible software application that
supports the search, browse and display of heterogeneous digital content.
XTF offers efficient and practical methods for creating customized end-user
interfaces for distinct digital content collections.
 
Highlights from the 2.1 release include:
* Extensive  interface improvements, including new search forms, built-in
faceted browsing,  and a new look and feel.
* Increased  support for document and information exchange formats.
> * XHTML  and OAI-PMH output
> * NLM  article format indexing and output
> * Microsoft  Word indexing
* Streamlined  XSLT stylesheets for simpler deployment and adaptation.
* Updated  documentation that has been moved to the XTF project wiki
<http://xtf.wiki.sourceforge.net/> , allowing XTF  implementers to share
solutions with entire user community.
* "Freeform"  Boolean query language, offered as an experimental feature.
* Backward  compatibility with existing XTF implementations.
>> A complete list of changes <http://xtf.wiki.sourceforge.net/changeLog_2.1>
>> is available on the XTF Project page on SourceForge
>> <http://sourceforge.net/projects/xtf/> , where the distribution (including
>> documentation) can also be downloaded.
>>  
>> Since the first deployment of XTF in 2005, the development strategy has been
>> to build and maintain an indexing and display technology that is not only
>> customizable, but also draws upon tested components already in use by the
>> digital library and search communities - in particular the Lucene text search
>> engine, Java, XML, and XSLT.  By coordinating these pieces in a single
>> platform that can be used to create multiple unique applications, CDL has
>> succeeded in dramatically reducing the investment in infrastructure, staff
>> training and development for new digital content projects.
>>  
>> XTF offers a suite of customizable features that support diverse intellectual
>> access to content.  Interfaces can be designed to support the distinct tools
>> and presentations that are useful and meaningful to specific audiences.  In
>> addition, XTF offers the following core features:
>> * Easy to deploy: Drops directly in to a  Java application server such as
>> Tomcat or Resin; has been tested on Solaris,  Mac, Linux, and Windows
>> operating systems.
>> * Easy to configure: Can create indexes on  any XML element or attribute;
>> entire presentation layer is customizable via  XSLT.
>> * Robust:  Optimized to perform well on large documents (e.g., a single text
>> that exceeds 10MB of encoded text); scales to perform well on collections of
>> millions of documents; provides full Unicode support.
>> * Extensible:  
>>> * Works  well with a variety of authentication systems (e.g., IP address
>>> lists, LDAP,  Shibboleth).
>>> * Provides  an interface for external data lookups to support
>>> thesaurus-based term  expansion, recommender systems, etc.
>>> * Can  power other digital library services (e.g., XTF contains an OAI-PMH
>>> data  provider that allows others to harvest metadata, and an SRU interface
>>> that  exposes searches to federated search engines).
>>> * Can be deployed as separate, modular pieces of a  third-party system
>>> (e.g., the module that displays snippets of matching  text).
>> * Powerful for  the end user:
>>> * Spell  checking of queries
>>> * Faceted  displays for browsing
>>> * Dynamically  updated browse lists
>>> * Session-based  bookbags
>> These basic features can be tuned and modified.  For instance, the same
>> bookbag feature that allows users to store links to entire books, can also
>> store links to citable elements of an object, such as a note or other
>> reference.
>>  
>> A sampling of XTF-based applications both within and outside of the CDL
>> include:
>>  
>> * Mark Twain Project Online <http://www.marktwainproject.org/>
>> (http://www.marktwainproject.org), developed by the Mark Twain Papers
>> Project,  the CDL and the University of California  Press.
>> * Calisphere <http://www.calisphere.org/>  (http://www.calisphere.org/),  a
>> curated collection of primary sources keyed to the curriculum standards of
>> Californiašs  K-12 community, developed by the CDL.
>> * The Encyclopedia of  Chicago <http://www.encyclopedia.chicagohistory.org/>
>> (http://www.encyclopedia.chicagohistory.org/), developed by the  Chicago
>> History Museum, The Newberry Library, and Northwestern University
>> * The Chymistry of Isaac  Newton <http://webapp1.dlib.indiana.edu/newton/>
