RDF: The Basics A new article by Ric Roberts offers an introductory-level explanation of RDF for newcomers to the Semantic Technology space. Roberts begins, “Linked Data is based around describing real world things using RDF. A lot of articles about Linked Data assume you already know what RDF is all about: if you are coming to it for the first time, this article explains the basics. RDF stands for Resource Description Framework. It’s a W3C standard for modeling information.” He continues, “RDF allows you to define statements about things (or resources), in the form of subject-predicate-object expressions (known as RDF-triples due to the 3 constituent parts).
microdata microdata is part of WHATWG's HTML living specification that provides another way to embed microformats and poshformats vocabularies, and has been superseded by microformats2. microdata was explicitly dropped by the W3C (and therefore not part of W3C HTML5) due to a lack of interest by anyone to edit the spec and keep it up to date. summary microdata consists of a set of attribute extensions to HTML: itemprop attribute is a more specific version of class, for field names subject attribute allows semantically linking within the page. The Huge, Unseen Operation Behind the Accuracy of Google Maps Inside Atlas, Google’s map-editing program, operators can see where Street View cameras have captured images (colored dots), and zoom in with a spyglass tool. Google Maps The maps we use to navigate have come a long way in a short time. Since the ’90s we’ve gone from glove boxes stuffed with paper maps to floorboards littered with Mapquest printouts to mindlessly obeying Siri or her nameless Google counterpart. The maps behind those voices are packed with far more data than most people realize.
Curation Reference Manual Access the Manual online So far, we have commissioned our network of specialist partners and associates to author more than 20 instalments of the Manual. We also welcome your suggestions for further topics. Completed chapters | Chapters in production Each instalment is designed to help data custodians, producers and users better understand the challenges they face and the roles that they play in creating, managing and preserving digital information over time. For each topic covered, suggestions for best practice and real life examples are given.
How RDF Databases Differ from Other NoSQL Solutions - The Datagraph Blog This started out as an answer at Semantic Overflow on how RDF database systems differ from other currently available NoSQL solutions. I've here expanded the answer somewhat and added some general-audience context. RDF database systems are the only standardized NoSQL solutions available at the moment, being built on a simple, uniform data model and a powerful, declarative query language. Microdata You are here: Home Dive Into HTML5 Diving In There are over 100 elements in HTML5. Some are purely semantic, others are just containers for scripted APIs. Throughout the history of HTML, standards wonks have argued about which elements should be included in the language.
The internet of things is here, but the rules to run it are not The first murder through the internet of things will likely take place in 2014, police service Europol warned this month. The crime could be carried out by a pacemaker, an insulin dosage device, a hacked brake pedal or myriad others objects that control life-and-death functions and are now connected to the internet. In control of a malicious hacker, any of these devices could give “killer app” a whole new meaning.
RDFa Primer 1 Introduction The web is a rich, distributed repository of interconnected information organized primarily for human consumption. On a typical web page, an XHTML author might specify a headline, then a smaller sub-headline, a block of italicized text, a few paragraphs of average-size text, and, finally, a few single-word links.
Swedish National Data Service Data management is a method used to handle, organise, structure and store research data throughout the research process. A good data management strategy takes into account technical, organisational, structural, legislative and sustainability aspects. It thus helps researchers to keep the data collected and/or used within their project tidy, useable and safe, while at the same time ensuring their longevity. SND’s data management pages are in Swedish only and this is for a good reason: The English-speaking already has access to a wealth of high-quality data management literature, both published and online. For your convenience, we have collected a selection of links to what we think are good resources for anybody wanting to learn more about data management. University of Bristol Research Data Bootcamp
RDF Web Applications Working Group Current and Upcoming Events Teleconferences: The first Thursday of each month at 10am US Eastern time. An agenda is sent to rdfa-wg 24 hours in advance; minutes follow within a day or two. Will be monitoring comments on any specification or test cases W3C Standards and Notes HTML+RDFa 1.1 (REC) About microdata - Webmaster Tools Help The HTML5 microdata specification is a way to label content to describe a specific type of information—for example, reviews, person information, or events. Each information type describes a specific type of item, such as a person, and event, or a review. For example, an event has the properties venue, starting time, name, and category. Microdata uses simple attributes in HTML tags (often <span> or <div>) to assign brief and descriptive names to items and properties. Here's an example of a short HTML block showing basic contact information for Bob Smith. <div> My name is Bob Smith but people call me Smithy.
The Phone Call Is Dead photo © 2008 mike | more info (via: Wylio) In the tech industry saying that something is dead actually means “It’s on the decline.” And yes, the phone call is on an inexorable decline. My original title for this post was “The Phone Call Will Be Dead In __ Years” but as consumer inertia is somehow still keeping our parent company Aol in the dialup business, I thought it might be prudent not to include an ETA on the death of the call. Less obsolete but more annoying than a handwritten letter, the phone call is fading as a mode of communication even if the nostalgic will be singing its praises for awhile. We reached a breaking point in 2008 when text messaging topped mobile phone calling in usage, and we’ve been living in a world dominated by text based communication ever since (Thanks Twitter). If old media has taught us anything, it’s that it takes most industries at least a generation to be completely disrupted, especially something as powerful as Big Telco.
poshformats poshformats are data formats constructed from the use of semantic class names. microformats Research Data Bootcamp Image: Twitter Data by Michael Gallagher This online tutorial is appropriate for all members of the University who undertake research with some kind of digital aspect.
