Gonzalo Moreno

My name is Gonzalo Moreno. I'm from MADRID, 34 years old; I studied all my life there, but now I live in Marbella (SPAIN) with great weather almost all the year!! My first experience with Coding started programming in "Basic" long long time ago; very easy video-games with very low quality graphics and so many lines of code by that time in order to get those poor results; by that time, even the "www" was something almost unknown, and I stopped coding completely; "Basic" was extremely boring to me. I became an Entrepreneur some years later, and got back to Programming Languages. I am very interested in developing my own Apps; at the moment, I'm working hard on a very interesting Application.

Generate Rich Snippets Easily. HTML5 Microdata Format Generator. Following up on a previous entry on the Microdata Format, I’ve created a completely free, for non-commercial purposes, Microdata Generator for some of the more popular item types: Books, Movies, People, Organizations and Companies, Stores, Restaurants, and Local Businesses.

HTML5 Microdata Format Generator

While there are other Microdata Generators and Creators out there, I haven’t found one that correctly nests multiple item types, or integrates the correct Hours of Operation (date/time) item property, which is essential for local businesses and restaurants. Furthermore, I’ve taken the extra step of giving you the option to include line breaks (for those who prefer the raw text format), the option to wrap the labels in a <span> tag, and the option to insert a class into the label span for custom css styling!

Promote Your Content with Structured Data Markup   Structured data refers to kinds of data with a high level of organization, such as information in a relational database.

Promote Your Content with Structured Data Markup  

When information is highly structured and predictable, search engines can more easily organize and display it in creative ways. Structured data markup is a text-based organization of data that is included in a file and served from the web. It typically uses the schema.org vocabulary—an open community effort to promote standard structured data in a variety of online applications. Structured data markup is most easily represented in JSON-LD format, which stands for JavaScript Object Notation for Linked Data. Training Direct from W3C. Full Hierarchy. Home.

Microdata - Dive Into 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. Should HTML include a <figure> element? The HTML5 Family: Microdata Overview. Microdata & the microdata DOM API. Introduction One of the main problems HTML5 set out to solve was consistency (and therefore machine-readability) of markup, evidenced by the introduction of standard semantic elements such as <header>, <nav> and <figure>.

Microdata & the microdata DOM API

This is all well and good, but there are times when you’ll want to add specific machine-readable data attributes to pieces of content so that they can be read consistently by some kind of processing script, even if the exact markup used differs slightly between different content. This need has already been satisfied to a certain degree, by the cleverly simple and backwards compatible Microformats, and the rather more esoteric RDFa.

But it is perhaps not a surprise that a tailored solution has been added to the HTML5 spec in the form of microdata, which includes a set of attributes that can be added to any element you wish, and an associated DOM API for processing/aggregating the microdata on a given page. HTML syntax. HTML5 Microdata and Schema.org. By Jason Ronallo Foundation HTML elements have semantics.

HTML5 Microdata and Schema.org

HTML Microdata. Abstract This specification defines the HTML microdata mechanism.

HTML Microdata

This mechanism allows machine-readable data to be embedded in HTML documents in an easy-to-write manner, with an unambiguous parsing model. It is compatible with numerous other data formats including RDF and JSON. Status of This document This section describes the status of this document at the time of its publication.

RDF 1.1 Lite Issue # 2: property vs rel from Guha on 2011-10-22 (public-vocabs@w3.org from October 2011) RDF 1.1 Lite Issue # 2: property vs rel Jason Douglas brings up one of the main points that lead us at Schema.org to support Microdata in favor RDFa, namely the distinction between rel and property. Google announced supported RDFa in 2009. One of the startling discoveries we made was that the error rate (i.e., webmasters marking up their pages to say X when the really meant to say Y) was about 3 times as much as it was for other formats (which include microformats, sitemaps, Google shopping feeds, etc.).

The error rate is/was so bad that we had resort to highly non-scalable techniques like having humans look at the markup on each site to make sure it said what the page said. Search engine optimization. As an Internet marketing strategy, SEO considers how search engines work, what people search for, the actual search terms or keywords typed into search engines and which search engines are preferred by their targeted audience. Optimizing a website may involve editing its content, HTML and associated coding to both increase its relevance to specific keywords and to remove barriers to the indexing activities of search engines. Promoting a site to increase the number of backlinks, or inbound links, is another SEO tactic. The plural of the abbreviation SEO can also refer to "search engine optimizers", those who provide SEO services.

History Early versions of search algorithms relied on webmaster-provided information such as the keyword meta tag, or index files in engines like ALIWEB. By relying so much on factors such as keyword density which were exclusively within a webmaster's control, early search engines suffered from abuse and ranking manipulation.
