Schema.org — Google, Microsoft and Yahoo! Agree On Markup Vocabulary 192

aabelro writes "Google, Microsoft and Yahoo! have decided to propose a common markup vocabulary, Schema.org, based on the Microdata format, simplifying the job of webmasters who want to give meaning to their web pages' content." Manu Sporny, chair of the W3C group that created RDFa, added his (personal) dissenting opinion about Schema, calling it a 'false choice,' and saying, "The entire Web community should decide which features should be supported – not just Microsoft or Google or Yahoo."

      The proposal is itself breaking html. This time, Google and Yahoo are in with the "extending". The vague promise of better search positions will drive web developers to completely muck up their html output. There is no reason not to re-use the Dublin Core [wikipedia.org].

        So they're breaking HTML by following the HTML5 specification [w3.org]?

        • Microdata is not part of the HTML5 specification. Right at the top of your linked document it says:

          Status: Controversial Working Draft. ISSUE-76 (Microdata/RDFa) blocks progress to Last Call

          and then if you click on the issue link, you see:

          There will be a forthcoming HTML5+RDFa proposal that may either be published along-side the Microdata specification or in place of the Microdata specification. RDFa is a alternate technology that is currently published as a Recommendation via the W3C . An additional alternative that is being proposed is the removal of Microdata and RDFa from the HTML5 specification and the placement of each section into a separate specification that is implemented on top of the HTML5 standard.

          In addition, the charter for the HTML WG mentions:

          "The HTML WG is encouraged to provide a mechanism to permit independently developed vocabularies such as Internationalization Tag Set (ITS), Ruby, and RDFa to be mixed into HTML documents. Whether this occurs through the extensibility mechanism of XML, whether it is also allowed in the classic HTML serialization, and whether it uses the DTD and Schema modularization techniques, is for the HTML WG to determine."

          The current microdata section precludes this Charter requirement.

      • HTML5 itself started off with WhatWG documenting the "breaking" browser specific extensions to HTML by various browsers... XmlHttpRequest is based on a non-standard MS active-x control. All of HTML itself is a series of non-compliant extensions later ratified... at least this time there are three disparate third parties behind it. If google, ms and yahoo are for it, it's probably not a bad thing... besides they've already been using this metadata for a while. though I think meta-* attributes to counterpa
      • To be fair, whatwg's "HTML is a living standard" bullshit was the first successful attempt at breaking HTML, and is in essence the exact same thing that these companies are proposing. So, it appears that everyone is trying to break up HTML to their own benefit.

    One of the reasons why Google was able to tromp AltaVista was that AltaVista's search was based completley on the MetaData tag of the html page, and Google ignored the MetaData tag. The reason why? Website administrator were putting false information into the MetaData tag in hopes of generating more web crawler search hits. Google decided to go off of what was actually being presetned on the page, and we all found that to be more useful.

      I guess it remains to be seen whether content sites will actually implement this, or whether it'll just be another tool in the black-hat SEO bag. I can see how this may be useful on, say, Wikipedia, which is content-dense and could be rapidly renovated; however, I kind of get the feeling that Wikipedia doesn't really need the help getting to the top of Google's results list.
      • I don't know about this specific format, but for example e-commerce companies have been annotating their pages with semantic tags. Best Buy, for example, has annotated a huge amount of data with the Good Relations ontology.

        And I don't really see how could this be abused, except for the boost that Google gives to any semantically tagged pages - but that effect should wear off as most sites implement them too.

      • It's not meant for hidden data but to mark a name as a name. People have been using microdata (or microformats) for awhile. It's not really taken off because it needed to be standardised as it is now. If there was any benefit to abusing the format it has already existed. I don't see any real benefit in relation to SEO other than things like indexing addresses and names easier so search for a person may be easier.
    • "More is better, except for hidden text" - I think this is the key difference between this and meta tags - the emphasis is on adding markup to text/content you provide to the user, in a way that makes it more quantifiable to search engines. Metatags weren't visable to the end user, and didn't particular concern specific content, but rather pages as a whole. I mean, that isn't to say that this system won't be scammed, but it does at least have a different focus of providing context for extant data, not additional data from which to help create a context.
      • It used to be very common for pages to have a few KB of point size 1, white-on-white text at the end, containing popular search terms. This didn't affect Google, because Google's algorithm placed more emphasis on the pages that linked to you than on the content of your page. The problem with this, is that it's also subject to gaming (lots of sites that do nothing but link to pages with popular search terms). Google had an early advantage because everyone was exploiting flaws in their competitors' algorit

            Well, that was how it was done in the mid-'90s. These days, you'd put the text in a SEO div that you would then remove via JavaScript. For extra points, you could remove it in response to a mouse move event or similar, so that even if the search engine's crawler used a JavaScript engine it would still see the fake text.

            There is also no suggestion that this markup will be the primary factor in ranking search results.

            The problem with that, is that metadata is only useful if things make use of it. If search engines are going to use it, that makes it worth a lot o

        Yes it is, generally speaking, hard to parse strings into date and time.

        What date or time does "Tomorrow", "Next friday", "7/5/09", "6 o 'clock", or "directly after lunch" refer to ? Keep in mind that the document may not be current - and make sure to take into account different time-zones and different conventions for dates. (in particular, some odd countries like to print dates as M/D/Y where the least-significant part is in the *middle*)

            Yeah. Though arguably even 31/12/1990 is suboptimal, it -does- have the advantage of not having the least-significant-part in the *middle*, but it still, for example, sorts wrong regardless of if you sort numerically or alphabetically.

        Really. Do you have a reliable parser for common date formats that works in all languages and scripts? If so I'd be keen for a reference.

        Or is this a comment by someone with the typical ASCII-is-all-we-need view of the world?

      • Yes, it is that hard to parse a timestamp. People are inconsistent. You might see "7:00" (unadorned), "7:00a", "7:00 AM", "7AM", "07:00", and "7 o'clock" all in the same document. And dates are nearly impossible. When is 1/2/11? January 2nd or February 1st? 2011 or 1911?

      Yes, we found that to be more useful - until website administrators learned to put false information into what is actually being presented on the page.

    • Microdata format isn't meant to be meta data in the sense of html metadata tags. It's for marking names as a first name and a surname. It allows you to pull an address for example out of a site straight into your email client. I'm sure someone may try to abuse it for better search rankings but I don't think it would work that well.

    But dammit, did it have to be microdata? I already mark up with microformat classes and RDFa (both the sortof standardized namespaces and Google's) and Google was handling it pretty well, and every once in a while it looked like Yahoo grokked it too. Microdata was the ugly stepchild third choice, the least well-supported one, with the fewest number of parsers out there in the wild.. So I left that one out, because nobody cared. Now it's going to be The One?

    I have better things to do than add Yet Another fucking attribute to my generated HTML which is already bloated with otherwise unnecessary classes and properties and typeofs. Now I'm going to have itemscope and itemtype attributes too, huh? Just how many characters long can we make each element become, just so that everything can make sense of it? Fuck you guys. No seriously, fuck you. Yes, I'm going to do it anyway, but even so, fuck you.

      You're right, it is a trap, but it gets worse:

      The short summary: The "Sponsors" (read: cartel) may have patents on this crap. You can, for now, use the crap royalty free for markup only if you follow the standard. Non-cartel search engines are not granted such rights. In addition, future versions may not be royalty free. Your existing markup is safe, but any new versions or pages won't be.

      The actual fine print:

      In addition, if the Sponsors have patent claims that are necessarily infringed by including markup of structured data in a webpage, where the markup is based on and strictly complies with the Schema, they grant an option to receive a license under reasonable and non-discriminatory terms without royalty, solely for the purpose of including markup of structured data in a webpage, where the markup is based on and strictly complies with the Schema.
