MVCnPHPProject - AptitudeCMS - Trac
MVCnPHP stands for Model-View-Controller in PHP and it is just that...an MVC implementation written in PHP. Not familiar with MVC? We'd recommend a quick read on Wikipedia. In a nutshell it's a design pattern that creates a clean separation between the presentation layer (screens) with the business logic layer (models). MVCnPHP is open source released under the New BSD License and you can see a demo of MVCnPHP in action.

Architectonic: Linked Data: End-User Applications?
This post is about is real end-user applications that take advantage of Linked Data. By "real" I mean something that sits on your desktop (or in your phone, or maybe even web browser) with a rich user interface tailored for a particular task. I don't mean generic browsers or infrastructure components.
BibClassify
BibClassify automatically extracts keywords from fulltext documents. The automatic assignment of keywords to textual documents has clear benefits in the digital library environment as it aids catalogization, classification and retrieval of documents.
BibClassify performs an extraction of keywords based on the recurrence of specific terms, taken from a controlled vocabulary. A controlled vocabulary is a thesaurus of all the terms that are relevant in a specific context. When a context is defined by a discipline or branch of knowledge then the vocabulary is said to be a subject thesaurus.

Facebook Connect Is Now Generally Available. Let the Identity Wars Begin | Epicenter from Wired.com
Facebook flipped the switch on its single sign-on technology Thursday. Facebook Connect can now be implemented by any site on the internet on a self-service basis through the company's platform for web developers.
The company says over 100 websites have added Facebook Connect during the testing period or will release it within the coming weeks. Several high-profile websites are on the list, including Digg, CNET, Gawker, Vimeo and several universities.
The system is a proprietary creation of Facebook, and it presents a challenge to the open source technology known as OpenID.

The Self-Describing Web
-
The Web is designed to support flexible exploration of information by
human users and by automated agents. For such exploration to be
productive, information published by many different sources and for a
variety of purposes must be comprehensible to a wide range of Web client
software, and to users of that software.
HTTP and other Web technologies can be used to deploy
resource representations that are self-describing:
information about the encodings used for each representation is provided explicitly
within the representation.
Starting
with a URI, there is a standard algorithm that a user agent can apply to
retrieve and interpret such representations.
Furthermore, representations can be what we refer to as grounded
in the Web, by ensuring that specifications required to
interpret them are determined unambiguously based on the URI, and that explicit
references connect the pertinent specifications to each other.
Web-grounding ensures that the specifications needed
to interpret information on the Web can be identified unambiguously.
When such
self-describing, Web-grounded resources are linked together,
the Web as a whole can support reliable,
ad hoc discovery of information.
This finding describes how document
formats, markup conventions, attribute values, and other data formats
can be designed to facilitate the deployment of self-describing,
Web-grounded Web content.

It is increasingly common for Web-based protocols to require the
discovery of policy or metadata before making a request. For
example, the Robots Exclusion Protocol specifies a way for automated
processes to obtain permission to access resources; likewise, the
Platform for Privacy Preferences [W3C.REC-P3P-20020416] tells user-
agents how to discover privacy policy beforehand.
While there are several ways to access per-resource metadata (e.g.,
HTTP headers, WebDAV's PROPFIND [RFC4918]), the overhead associated
with them often precludes their use in these scenarios.
When this happens, it is common to designate a "well-known location"
for such metadata, so that it can be easily located. However, this
approach has the drawback of risking collisions, both with other such
designated "well-known locations" and with pre-existing resources.
To address this, this memo proposes a single (and hopefully last)
"well-known location", /host-meta, which acts as a directory to the
interesting metadata about a particular authority. Future mechanisms
that require authority-wide metadata can easily include an entry in
the host-meta resource, thereby making their metadata cheaply
available (indeed, because it can be cached, the more mechanisms that
use it, the more efficient it becomes) without impinging on others'
URI space.
Note that the metadata provided by a host-meta resource is explicitly
scoped to apply to the entire authority (in the URI [RFC3986] sense)
associated with it (using the process described in Section 4); it
does not apply to a subset, nor does it apply to other authorities
(e.g., using another port, or a different hostname in the same
domain). However, individual mechanisms (e.g., a relation type in
the Link field) MAY reduce or expand this scope. This should only be
done after careful consideration of the consequences upon security,
administration, interoperability and network load.
Business Models on the Web | Professor Michael Rappa
-
Business models are perhaps the most discussed and least understood aspect of the web. There is so much talk about how the web changes traditional business models. But there is little clear-cut evidence of exactly what this means.
In the most basic sense, a business model is the method of doing business by which a company can sustain itself -- that is, generate revenue. The business model spells-out how a company makes money by specifying where it is positioned in the value chain.

How we'll live when information surrounds us
Recorded at the ALA MidWinter 2009 OCLC Symposium
The Web, and how we use it, has changed dramatically over the past few years. We've seen explosive growth in social networking, more types and volumes of content becoming available, a wider availability and sophistication of creative tools and the growing use of mobile devices to access the Internet. Taken individually, each of these changes represents a major shift in how we learn and communicate. Together, these trends signal a shift to a future where the Web is at the center of our information lives.
What does that mean for us as learners, educators, citizens and creators? How will our lives be changed when we don't connect to information on a case-by-case basis, but live in an environment saturated with data, media and communications?
OCLC invited David and Nova to share a preconference conversation with us. Their dialogue (PDF download) touches on several key concepts related to the future of the Web and how we'll share information and ideas.
VISSW 2009: Visual interfaces to the Social and the Semantic Web
-
This workshop aims to bring together researchers and practitioners from different fields, such as Human-Computer Interaction, Information Visualization, Semantic Web, and Personal Information Management, to discuss latest research results and challenges in designing, implementing, and evaluating intelligent interfaces supporting access, navigation and publishing of different types of contents on the Social and Semantic Web. In addition, the workshop also serves as an opportunity for researchers to gain feedback on their work as well as to identify potential collaborations with their peers.

The Code4Lib Journal - Affinity Strings: Enterprise Data for Resource Recommendations
-
The University of Minnesota Libraries have created a MyLibrary portal, with databases and e-journals targeted to users, based on their affiliations. The University’s enterprise authentication system provides an “affinity string”, now used to personalize the MyLibrary portal. This affinity string automates discovery of a user’s relationship to the University–describing a user’s academic department and degree program or position at the University. Affinity strings also provide the Libraries with an anonymized view of resource usage, allowing data collection that respects users’ privacy and lays the groundwork for automated recommendation of relevant resources based on the practices and habits of their peers.
