ToDo/Wish List


Thank you for your great work here, I have one question, should I be able to see the semantic data somewhere in my Doku, or does it all happen in the background after this plugin is loaded? Thank you so much! — John Morris 2016-01-08 17:47
The same question here too. - Florin 2016-02-20
This plugin adds semantic data (structured data) in your DokuWiki pages, to increase the search engine visibility:

* via Standard HTML <meta/> tags (to add Author, Description, etc)
* via Dublin Core metadata Dublin Core
* via JSON-LD with metadata (for License, Author, Description, Search, etc)

To see Semantic Plugin in action, use Google Structured Data Testing Tool. This tool analyze your DokuWiki pages and display the structured data added by Semantic Plugin.

In alternative use CTRL+U in your browser to see the source :) Giuseppe Di Terlizzi 2016-02-21
I'm grateful to you for your work. I have one question. Can this plugin add Open Graph image metadata?
If not, I think it is better that become to make first image as OpenGraph image-tag.
 Hi, i have added og:image tag in v2017-05-23 release.

I saw new release. It's good. Thanks you. And I noticed one problem.
It can't refer an external image on top of the page. There is a character entity references matter like thet “&amp;” become “&amp;amp;”.
I don't know what is meant by “AJAX Service”. Has it to be implemented? And what is “exposeWebService”?
