Facebook's Graph API: The Future Of Semantic Web?
“There are two important themes behind everything we're delivering today.” says Bret Taylor, head of Facebook’s platform products in the facebook developer blog, about the recent announcements at the f8 conference in San Francisco. Facebook introduced Open Graph protocol, and the Graph API as the next evolution in the Facebook platform. First, the Web is moving to a model based on the connections between people and all the things they care about. Facebook introduced three new components of Facebook Platform two of which the Open Graph protocol, and the Graph API. Excerpted from the Graph API page are some examples of URI’s for accessing facebook obects (resources) using their identifiers. All objects in Facebook can be accessed in the same way:[…] All of the objects in the Facebook social graph are connected to each other via relationships. The URI’s also have a special identifier me which refers to the current user. Reactions from the web have been positive in general.

Semantic Web Patterns: A Guide to Semantic Technologies
In this article, we'll analyze the trends and technologies that power the Semantic Web. We'll identify patterns that are beginning to emerge, classify the different trends, and peak into what the future holds. In a recent interview Tim Berners-Lee pointed out that the infrastructure to power the Semantic Web is already here. ReadWriteWeb's founder, Richard MacManus, even picked it to be the number one trend in 2008. And rightly so. The Semantic Web means many things to different people, because there are a lot of pieces to it. The disagreement is not accidental, because the technology and concepts are broad. 1. We have written a lot about the different approaches to the Semantic Web - the classic bottom-up approach and the new top-down one. A big win for the bottom-up approach was recent announcement from Yahoo! Another recent win for the bottom-up approach was the announcement of the Semantify web service from Dapper (previous coverage). 2. 3. 4. 5. 6. 7. Conclusion
Web 3.0: When Web Sites Become Web Services
Today's Web has terabytes of information available to humans, but hidden from computers. It is a paradox that information is stuck inside HTML pages, formatted in esoteric ways that are difficult for machines to process. The so called Web 3.0, which is likely to be a pre-cursor of the real semantic web, is going to change this. The transformation will happen in one of two ways. The Amazon E-Commerce API - open access to Amazon's catalog We have written here before about Amazon's visionary WebOS strategy. Why has Amazon offered this service completely free? The rise of the API culture The web 2.0 poster child, del.icio.us, is also famous as one of the first companies to open a subset of its web site functionality via an API. The del.icio.us API offering today is different from Amazon's one, because it does not open the del.icio.us database to the world. Standardized URLs - the API without an API Delexa is an interesting and useful mashup that uses del.icio.us to categorize Alexa sites.
Semantify - Automate Your Semantic Web SEO in Five Minutes
The timing couldn't be better for the release of Semantify, a new service from Israel/San Francisco's Dapper.net. One week after Yahoo! announced that it will begin indexing the semantic markup and meaning of content on the web, Semantify offers a remarkably simple way to get your website marked up semantically. Automatically, forever. Once you learn how to use Dapper's basic interface, it can take less than five minutes to set up the Semantify service. Just a Few Steps Here's what it takes: 1. 2. 3. 4. And then you're done. Dapper GUI + Semantic Web vocab list + PHP embed code = automated Semantic Web markup for your site. It's The Early Days It's as simple as that, or at least it will be once all the little kinks are worked out. You can go through those steps above today, I have, and whenever the Yahoo! Historical Context Many people have questioned the viability of the Semantic Web vision, asking who will do the markup. The Semantic Web could change the world.
Enhancing documents with annotations and machine-readable structured information using Notate
Summary Textensor Limited is developing tools for improving the communication and exploitation of text based information. Our main product, Notate, is a web based system that enables authors and readers to layer structured annotations on top of documents so that the resulting combination can be reliably processed automatically while maintaining the integrity of the original source and the provenance of all annotations. The system has a wide variety of applications including attaching sticky notes and discussions to web pages, sharing documents and notes within a small group, on-line document review and sophisticated data curation tasks. It aims to bring the authoring of semantically rich structures within the capabilities of normal users, making it dramatically easier to produce well-structured content and opening up possibilities for further automated processes such as creating indexes to the research literature and curating more high-quality information into databases.

C ACL System
Abstract The HTTP protocol is a network resource access protocol that leaves user authentication and access validation entirely up to the server. There is no guarantee that authentication realms are related to directory or even consistent over time. Status of this Document This document is a description of the W3C ACL system, but does not consitute an endorsement or recommendation of any sort. The exact revision of document may be identified by the CVS version $Revision: 1.30 $. Table Of Contents Goals ACLs are designed to express access rules in a logical, unambiguous, machine-accessible format. Structure An access system may be divided into: Identity Management Maintaining identity information. Group Association Lists of which identities and groups lie within which other groups. Privilege Management Semantic Web Implications A resonable semantic web algae query for determining an identity's access privileges would be, for a given resource: Find the ACL rules for that resource. uris acls hierarchy
