Web Data Commons. RDFa 1.1 Primer. We begin the introduction to RDFa by using a subset of all the possibilities called RDFa Lite 1.1 [rdfa-lite]. The goal, when defining that subset, was to define a set of possibilities that can be applied to most simple to moderate structured data markup tasks, without burdening the authors with additional complexities. Many Web authors will not need to use more than this minimal subset. 2.1.1 The First Steps: Adding Machine-Readable Hints to Web Pages Consider Alice, a blogger who publishes a mix of professional and personal articles at 2.1.1.1 Hints on Social Networking Sites Alice publishes a blog and would like to provide extra structural information on her pages like the publication date or the title.
Example 1 <html><head> ... This information is, however, aimed at humans only; computers need some sophisticated methods to extract it. Example 2 <html><head> ... (Notice the markup colored in red: these are the RDFa "hints".) Example 3 Example 4 Example 5 Example 6. RDF - Semantic Web Standards. Overview RDF is a standard model for data interchange on the Web. RDF has features that facilitate data merging even if the underlying schemas differ, and it specifically supports the evolution of schemas over time without requiring all the data consumers to be changed. RDF extends the linking structure of the Web to use URIs to name the relationship between things as well as the two ends of the link (this is usually referred to as a “triple”). Using this simple model, it allows structured and semi-structured data to be mixed, exposed, and shared across different applications.
This linking structure forms a directed, labeled graph, where the edges represent the named link between two resources, represented by the graph nodes. This graph view is the easiest possible mental model for RDF and is often used in easy-to-understand visual explanations. Recommended Reading The RDF 1.1 specification consists of a suite of W3C Recommendations and Working Group Notes, published in 2014. Web page classification. Content management system. CMSs are often used to run websites containing blogs, news, and shopping. Many corporate and marketing websites use CMSs. CMSs typically aim to avoid the need for hand coding but may support it for specific elements or entire pages. Main features[edit] The function and use of content management systems is to store and organize files, and provide version-controlled access to their data.
A CMS may serve as a central repository containing documents, movies, pictures, phone numbers, scientific data. Distinguishing between the basic concepts of user and content, the content management system (CMS) has two elements: Content management application (CMA) is the front-end user interface that allows a user, even with limited expertise, to add, modify and remove content from a Web site without the intervention of a Webmaster.Content delivery application (CDA) compiles that information and updates the Web site.
Web content management system[edit] Component content management system[edit] See also[edit] Hnews_analysis. An Analysis of hNews Usage - Max Cutler. On Wednesday, Martin Moore, one of the creators of the hNews microformat, posted on Idea Lab about how hNews is in use at 577 U.S. news sites. As someone who has long been interested in standardized markup and interchange formats for news content, I found this interesting and set out to investigate for myself. Moore’s post contains a link to a Google document containing a list of the 577 sites. I downloaded this spreadsheet as a CSV for easy consumption and analysis, and set to work. Duplicates/Sub-sites First thing I noticed is that there are 25 entries whose domain is already mentioned previously in the list.
CMSs Then I started randomly going to sites in the list, and noticed that many of them look remarkably similar. I came up with simple heuristics for determining which CMS powered a site (e.g., by looking for references to the CMS company’s domain in a CSS stylesheet or Javascript file link).
