  • What is Structured Data?
    2 projects | dev.to | 29 Oct 2021
    Web pages are an interesting example of both structured and unstructured data. There are specific elements one could look at for certain information like the element or other semantic elements like or . The problem though is that these elements are more like our "address" example earlier - they often contain more than just the strict data we are looking for. A title might have a prefix or suffix of the website's name. An article or section might have many other layers of
    , or any other elements to help form the site's structure. To top it off, the HTML structure can vary wildly from site to site. If you were wanting to extract data from multiple websites, it can get very hard very fast.

    That said, there are a number of ways to embed structured data into web pages. A web page could use Microdata, RDFa, JSON-LD or Open Graph to express structured data. More than that though, a web page can use multiple of these at the same time. Open Graph is commonly used as a method of defining details for a link preview while the others might express more complex data like product pricing or reviews.

    Having standard formats like Microdata or JSON-LD are a good start but only represent the format of the data - we need a common vocabulary so we can understand the data those formats encode. One common vocabulary used is called Schema.org and provides over 700 types including types to describe people, places, products, recipes, reviews, vehicles, movies and medical devices. Using Schema.org for structured data on a website can help search engines provide richer experiences in the search results.

    Summary

    Structured data, through standardising expected properties and value formats, makes the sharing and processing of data easier. Web pages in particular benefit from encoding structured data in their mark-up where it can be used by search engines and other tools.

  • Json-ld spices up the staticness of static site generator
    4 projects | dev.to | 27 Oct 2021
    Json-ld is a linked data format based on json. If you have never heard of json-ld, that's ok. The most important thing to know is that it's just plain old json with a few extra special fields. It's also a w3c standard and you can check out the complete spec. We don't really need to understand the whole spec, we're just interested in the way json-ld can reference other data fragments with a url using the keyword "@id "
  • Schema.org json-ld static site generator
    2 projects | dev.to | 10 Oct 2021
    Sambal natively supports schema.org json-ld as the content model so you can render webpage directly from any schema.org json-ld data. By using the open and well known schema.org vocabularies to structure your content from day one, it saves you the trouble of modeling your own content and later realizing it's not compatible with anyone else's content.
  • What is Structured Data for Advanced SEO?
    1 project | dev.to | 8 Aug 2021
    JSON-LD is a format to create a unified structured data vocabulary for the web. If you want to read more about JSON-LD, then read this https://json-ld.org/. But I want to focus here on how you can use it in your projects to use SEO for maximum traction.

    Order of formats matters. The first is the returned format by default, so in this case default returned data is in ld+json format (instead of plain json). It's simply better ;-) (here's why)

  • The common misconception about TypeScript

    Implement dynamic schema validation system and let the front-end fetch infer the schema from the backend and change it's validation flow accordingly, by this way you can avoid changing schema at multiple places. Check [https://json-ld.org/] for a similar analogy.
  • Launch HN: Athens Research (YC W21) – Open-Source Roam Research
    16 projects | news.ycombinator.com | 2 Mar 2021
    I've been thinking of a tool to generate a kind of schema for a website, similar to RDF[0] or JSON-LD[1]. The end goal of this would be interoperability between tools - ideally I could browse HN and other related sites or forums in my RSS reader with a unified interface, or translate the Roam note format into the Athens equivalent to use with either.
