My site is https://www.liteshop.com.au/content/olight-h15s-wave-rechargeable-led-headlamp We implemented rich snippets on my site seven weeks ago but still Google does not show on search. Testing tool shows "All good".

right doctype for RDFa breadcrumbs navigation and validator

由 我与影子孤独终老i 提交于 2019-12-02 08:10:34
问题 I need to make my mind clear about HTML doctypes. in this page: http://kovo.intl.uk.to I add breadcrumbs navigation using RDFa. but then page was no more valid. I googled and I found out to change doctype to: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML+RDFa 1.0//EN" "http://www.w3.org/MarkUp/DTD/xhtml-rdfa-1.dtd"> Now the page is 100% valid, but what means XHTML and such LOW number? At my webpages I am using HTML 4.01 strict due I write pages mostly in Slovak for Slovak people and what I see on

RDFa OfferCatalog Syntax

由 荒凉一梦 提交于 2019-12-02 04:22:39
I have been trying to find the best way to link two items together using RDFa, specifically linking a Person to multiple SoftwareApplication entries. The way I currently do this on the author page is: <div class="container text-center" vocab="http://schema.org/" typeof="Person"> ... <span property="hasOfferCatalog" typeof="OfferCatalog"> <meta property="numberOfItems" content="10" /> <span property="itemListElement" typeof="CreativeWork"> <meta property="name" content="Project Name" /> <meta property="url" content="https://www.my-domain.tld/ProjectName/" /> </span> ... As above the project is

How does schema.org usage fit into Linked Data principles?

由 别来无恙 提交于 2019-12-01 04:17:49
I am starting to learn schema.org schema. I come from the RDF/OWL community. To my surprise I could not indeed find an RDFS or OWL vocabulary representation of schema.org. More specifically, I realised that it was just a HTML page describing the schema. I also found an RDFa representation of the schema. Not sure that it can be a legal RDFS representation by the way. All of this got me a bit confused. In the meantime I found the following works: http://topbraid.org/schema/ and http://schema.rdfs.org/ . Hence I have the following few questions: 1- Are both work achieving the same thing? if not

What is the relation between Schema.org, Goodrelations-vocabulary.org and Productontology.org?

由 依然范特西╮ 提交于 2019-11-30 19:55:34
问题 What is the relation between Schema.org, Goodrelations-vocabulary.org and Productontology.org? Schema.org informs, "W3C schema.org Community Group is the main forum for the project". Google, Microsoft, Yahoo and Yandex are founding companies. Are Google, Microsoft, Yahoo and Yandex accepting Goodrelations-vocabulary.org and Productontology.org standard as well? If not, is it good idea to use them for future? Although Google did not mention, I read that there are some differences regarding

Microdata, RDFa or JSON-LD Appropriate or best usage?

由 烈酒焚心 提交于 2019-11-28 03:26:40
I have been wondering which of those formats is "best"? Schema.org, Microdata, and RDFa are bit of a pain to implement. They can break validation and require quite an effort to put into documents. JSON-LD is, at last for me, a way better to implement structured data. But does it work? What level of support is there for it (at least by Google)? unor Schema.org is a vocabulary that can, like any other vocabulary, be used in many forms. The website http://schema.org/ has examples using Microdata and the RDF syntaxes RDFa and JSON-LD , but these are not the only syntaxes it can be used with. You

Statistics about “Microformat vs HTML+RDFa” adoption

由 ＊爱你＆永不变心＊ 提交于 2019-11-27 15:14:13
问题 Are there some recent and reliable statistics about "Web use" (webpages using one standard or another) of these standards? Or an specific statistic about vCard (person and/or organization) scope of use? Only statistics , this question is not about "what the best ideia?" or "how to use it?". Looking for statistics numbers to compare Microformats adoption with (any kind of) RDFa in HTML adoption. We can considere, for "counting pages" statistics, that Microdata is a kind of RDFa-HTML.

Concepts for RDFa DRY references

由 自古美人都是妖i 提交于 2019-11-27 07:31:29
问题 I started digging into RDFa recently and try to spice my website with semantic information. The site offers services, events, a blog and may offer products in future. Happily schema.org has coarse but adequate categories for it all. But now it comes to practical questions. All the examples have all information on a single page, which seems pretty academic to me. E.g. on my landing page is a list with upcoming events. Events have a location property. My events run at 2 different locations. I
