The goal, when defining that subset, was to define a set of. Many Web authors will. The First Steps Adding Machine Readable Hints to Web Pages. Consider Alice, a blogger who publishes a mix of professional and personal articles. We will construct markup examples to. Alice can use RDFa. A more complete markup of these examples is. Hints on Social Networking Sites. Alice publishes a blog and would like to provide extra structural information on. She would like to use the terms. Dublin Core vocabulary dc. Her blog already. Example 1lt html. The Trouble with Boblt h. Date 2. 01. 1 0. This information is, however, aimed at humans only computers need some. But, using RDFa, she can annotate her. Example 2lt html. The Trouble with Boblt h. Date lt span propertyhttp purl. Notice the markup colored in red these are the RDFa hints. One useful way to visualize the structured data is. Figure 2 A visualization of the structured data. The Trouble with Bob and a creation date. Fig. 2relationship value is text. It is worth emphasizing that RDFa uses URLs to identify just about everything. This is why, instead of just using properties like title or. The reason behind this design. Using URLs removes the possibility for ambiguities in terminology. Without. ensuring that there is no ambiguity, the term title might mean the title of a. When each. vocabulary term is a URL, a detailed explanation for the vocabulary term is just. It allows anything, humans or machines, to follow the link to. By using a URL to identify a. URL unambiguously refers to the Date of creating the. By using URLs as identifiers, RDFa provides a solid way of disambiguating. It becomes trivial to determine whether or not vocabulary terms. If the URLs are the same, the. It also becomes very easy to create new. If one can publish a document to the. Web, one automatically has the power to create a new vocabulary document. Links with Flavor. The previous example demonstrated how Alice can markup text to make it machine. She would also like to mark up the links in a machine readable way, to. RDFa lets the publisher add a flavor. This. makes the same markup help both humans and machines. In her blogs footer, Alice already declares her content to be freely reusable. The HTML includes. Creative Commons cc about license. Example 3lt p All content on this site is licensed under. Creative Commons Licenselt a. Alice Birpemswick. A human clearly understands this sentence, in particular the meaning of. Unfortunately, when Bob visits Alices blog, his browser sees only a plain link. Alices friends or to her CV. For Bobs. browser to understand that this link actually points to the documents licensing. Alice needs to add some flavor, some indication of what. She can add this flavor using again the property attribute. Indeed. when the element contains the href or src attribute. The. value of the attribute is the http creativecommons. Creative Commons. Example 4lt p All content on this site is licensed under. City Of Heroes Costume Designer Salary. Creative Commons Licenselt a. Alice Birpemswick. With this small update, Bobs browser will now understand that this link has a. Figure 3 A link with flavor the link indicates. We can represent web pages as nodes, the link as an. Fig. 3two Web pages connected by a link labeled license and two notes with a license relationship. Alice is quite pleased that she was able to add only structured data hints via. RDFa, never having to repeat the content of her text or the URL of her clickable. Setting a Default Vocabulary. In a number of simple use cases, such as our example with Alices blog, HTML. However, while generating. URLs via a CMS system is not a particular problem, typing these by hand may. To alleviate this problem RDFa introduces. HTML. Thus, instead of. Example 5lt html. The Trouble with Boblt h. Date lt span propertyhttp purl. Alice can write. Example 6lt html. The Trouble with Boblt h. Date lt span propertycreated 2. Note how the property values are single terms now these are simply. URL defined via the vocab attribute. The. attribute can be placed on any HTML element i. Default vocabularies and full URIs can be mixed at any time. I. e., Alice could. Example 7lt html. The Trouble with Boblt h. Date lt span propertyhttp purl. Perhaps a more interesting example is the combination of the header with the. Example 8lt html. The Trouble with Boblt h. Date lt span propertycreated 2. All content on this site is licensed under. Creative Commons Licenselt a. Alice Birpemswick. The full URL for the license term is necessary to avoid mixing vocabularies. As. an alternative, Alice could have also chosen to use the vocab. Example 9lt html. The Trouble with Boblt h. Date lt span propertycreated 2. All content on this site is licensed under. Creative Commons Licenselt a. Alice Birpemswick. Note. The vocab attribute references structured data vocabularies, identified using URLs. RDFa does not limit the form of these URLs or the document formats accessible by de referencing them. SHOULD aim to use widely shared, conventional values for identifying such vocabularies. Multiple Items per Page. Alices blog page may contain, of course, multiple entries. Sometimes, Alices. Eve guest blogs, too. The front page of the blog lists the 1. How, then. should Alice mark up the title of each of these entries individually even though. RDFa provides resource, an. URL to which the. RDFa markup applies. Example 1. 0lt body vocabhttp purl. The trouble with Boblt h. Date lt span propertycreated 2. Alicelt h. 3. Jos Barbecuelt h. Date lt span propertycreated 2. Evelt h. 3. Note that we used relative URLs in the example the value of. URLs, i. e., relative or. We can represent this, once again, as a diagram connecting URLs to. Figure 4 Multiple Items per Page each blog entry. Fig. 4two separate nodes, each with two properties. Alice can use the same technique to give her friend Bob proper credit when she. Example 1. 1lt div resourcealicepoststroublewithbob. The trouble with Boblt h. The trouble with Bob is that he takes much better photos than I do. Beautiful Sunsetlt span. Boblt span. Notice how the innermost resource value. Once again, here is a diagram that represents the. Figure 5 Describing a Photo. Fig. 5two separate nodes, each with two properties. Exploring Further Social networks. Alice would also like to make information about herself, such as her email. This time, instead of describing the properties of a. Alice already has contact information displayed on her blog. Example 1. 2lt div. Alice Birpemswick. Email lt a hrefmailto aliceexample. Phone lt a hreftel 1 6. The Dublin Core vocabulary does not provide property names for describing contact. Friend of a Friend foaf vocabulary does. Alice therefore. decides to use the FOAF vocabulary. As a first step, she declares a FOAF. Person. For this purpose, Alice uses typeof, an RDFa attribute. Example 1. 3lt div typeofhttp xmlns. Person. Alice realizes that she only intends to use the FOAF vocabulary at this point, so. Example 1. 4lt div vocabhttp xmlns. Person. Then, Alice indicates which content on the page represents her full name, email.
