  • (2020-01-08) Thomas TRIAU: 100% CPU usage too
  • (2017-08-20) Jarno Le ContĂ©: 100% CPU usage
  • (2017-01-10) Mark Tippetts: Parses microdata as raw JSON-LD with colorized text. I like the styled formatting. That's a nice touch. Unfortunately, it seems to slow things down quite a bit on first loading (something is, anyhow). Unfortunately, I noticed one serious flaw: if there is more than one embedded object of the same type, only the first is displayed.
  • (2015-04-15) BĂ©renger Zyla: Often pushes the CPU to 100% when Chrome runs in the background. Seems really random. Have to kill the Google Chrome Helper process, and bubble shows up saying that the extension crashed and gives ability to reload the extension. Wish it were really more stable.
  • (2015-03-11) Scott Taylor: Pegs my CPU at 99-100%
  • (2015-03-10) Chirag Patel: It is work with only microdata. Not working with Json-Ld sniffer with javascript
  • (2015-01-12) Meraj Khan: Some times if does not reveal any semantic markup, but when it does its comprehensive.
  • (2014-12-02) Ronaldo Smithington: doesn't detect anything, causes unexpected end of line error on any page I visit.

    It would be awesome if you could display not only in json-ld but also so the onsite schema in a nice format to show microdata hierarchy.
  • (2015-01-20, v:1.0.1) Jarno van Driel: adding support for itemprop-reverse
    Hi Matthis, My name is Jarno van Driel, Semantic SEO and substantial contributor to the further development of schema.org over at the W3 schema.org discussion group: https://lists.w3.org/Archives/Public/public-vocabs/ I would like to ask you if you would consider adding support to your extension for a new proposed microdata attribute: @itemprop-reverse. This attribute does more or less the same as the @itemprop only in reversed order. More about this can be read on: http://www.w3.org/wiki/WebSchemas/InverseProperties The reason why I ask if you would consider adding support for it, is because of the approval process over at the W3. For this property to get accepted by the W3 and added to the microdata specs, we (the schema.org discussion group) need to show there are multiple tools out there that are able to consume this property. First to support this new property upfront is the Structured Data Linter: http://linter.structured-data.org/, but unfortunately this isn't enough to build a proper case yet. And hence my message to you. Hoping to hear from you, Jarno van Driel [email protected]
