This is something I've pondered over for a while, as I've seen both used in practise. Method 1 <ol> <li>List item 1</li> <li>List item 2 <ol> <li>List item 3</li> </ol> </li> <li>List item 4</li> </ol> This seems semantically correct to me, since the sub-list is a sub-list of that list item...
I'm setting up a blog, and I'm fascinated by RDF and the idea of the sematic web. I'd like to use RDFa to embed sematic data into my blog. There are several well know semantic web ontologies like FOAF for decribing people, ical for events, geo for places. Is there an ontology for blogs? Something to say "This site is a blog. Foo is a bl...
I understand that the goal of moving towards <div> tags from <table> makes sense since it is more semantic. However, I don't understand the benefit gained if you still need a clearing block to make column-based layouts work. For example: <!-- Note: location-info & personal-info both float left. --> <div class="contact"> <div class=...
The Problem I love using markdown to write questions, answers, posts, comments etc. That being said, I am a very technical, detail oriented, programmer type. However, I am working on a CMS of sorts to be used by non-technical folks. I am using Markdown for this, but I'm becoming increasingly worried that it will be too technical for ...
So I've tried to work with the pure-CSS, never-use-tables-for-layout gospel, I really have. But after an incredible amount of pain and anguish, I'm just about ready to give up. I'm willing to go to some effort to accomplish things in CSS, don't get me wrong. But when it seems like some of the most asininely simple things that can be d...
Hello, I'm looking to represent some domain model objects in a web app I'm writing and I'm looking for best-practices for markup. For example in yaml: --- !ruby/object:User email: [email protected] first: John last: Doe login: jdoe member_since: 2009-01-22 00:54:08.128094 -05:00 What would be a sensible way to present this? Or the bes...
Given the recent 55 minute Google service interruption, it seems obvious to me that internet search is too important to leave in the hands of one company (no matter how hard they try not to be evil). So are there some (possibly p2p) free open source alternative internet search/information storage and retrieval systems that might work or...
I've seen a lot frameworks to create a semantic web (or rather the model below it). What tools are there to create a small semantic web or repository on the desktop, for example for personal information management. Please include information how easy these are to use for a casual user, (in contrast to someone who has worked in this area...
I'm working with FOAF and RDFa, and struggling to figure out whether I should be using foaf:depiction or foaf:depicts and the correct way to use them. Here's what I've already established: <div class="profile" typeof="foaf:Person"> <p>Employee Name: <span property="foaf:name">Fred Flintstone</span></p> <p><img src="http://www.example.co...
There exists a pre-defined norm for RDF Schema. I was wondering whether RDF data instance does have RDF Schema snippet embedded in it? Something like name of a class which also happens to be the name of a subject/object. ...
I've heard a lot about the semantic web but I'm still not exactly sure what it is. How will it be different to the web we know now? ...
If you're selling widgets, we all know that having "Bob's Widgets" in the title and the H1 gives you a better ranking in Google when people search for "widgets". But what if, as someone explained to me the other day, their product is known by different names in different parts of the world? In the US, it's called a Widget. In Canada, i...
Hi, I'm doing a project on RDF, and got acquainted with the Web 3.0 (also known as Semantic Web) notion. I also got to read that Web 3.0 is something which Tim Berners Lee had in mind which came out as Web 1.0. Web 1.0 was internet in its formative years when users could just read and share information over web pages. Web 2.0 had inte...
I am new to Semantic Web. I want to start working on creating some basic RDF document and publish them to get a feel how it works.I found a lot of information about the concepts,vocabulary etc but I couldn't find any thing related to development as what is the development environment required, what are the tool required. I am from .net b...
Hi all I'm developing a script that extracts the messages from the message archive of a particular meetup.com group of which I'm a member - http://www.meetup.com/opencoffee/messages/archive/ The idea is to dynamically add these to a wordpress site and allow people to search messages, auto tag messages etc. The issue I have is how best...
I knew this might be a stupid question but I don't know the answer :) I am using protege4 I built my ontology and when I tried to use DL Query from the DL query tap in protege4 it executes fine and I get results. However, when I click "Add to ontology" to add my query to the ontology it adds it but without any query results!!! Why are...
I am developing an ontology and I have a problem with my Dl query there is a class called "flower" and this class has subclasses which are some flowers names and also there is another class called "flowersColor" and it has these values ("red","green" and "blue") as individuals-not subclass- every flower has one color or more I wan...

For those of you working on Semantic Web development, which C# tools do you use for reasoning, parsing, etc.? The idea is to build a central repository of all C# APIs currently available. Sort of like I did here. Please post links, if you can, so I am able to summarize correctly. ...
