 Schema.org is a project run by a consortium of search engines. Schema.org has created an extensive library of schemas that web-masters can use to explicitly mark-up their websites content in order to improve search engine visibility and interoperability.
 
 Bioschemas is an initiative to supplement the work of schema.org to help improve the findability of online resources in the life sciences.

 If your domain is not life sciences, your materials can still use these Bioschemas profiles. See [schemas.science](https://schemas.science) for domain-agnostic profiles. The Course, CourseInstance and TrainingMaterial profiles in schemas.science are equivalent to the Bioschemas profiles of the same name.

+## Sitemaps
 
 To help search engines (and TeSS) discover all the pages on a site that have Bioschemas markup, a [sitemap](https://developers.google.com/search/docs/crawling-indexing/sitemaps/overview) should be used. Sitemaps are basically a directory listing of all the pages on your site.
 
-Sitemaps are a well-established standard, and there should be sitemap libraries and plugins available for whichever software you are using to provide your site.

+## Calendar
 
 Many organisations use calendar applications to organise and display their events. These may be custom-made or, more likely, utilise applications like Google Calendar. Calendar applications maintain an underlying file for event storage and retrieval, typically in the iCal (.ics) format.
 
-TeSS can extract event descriptions, dates and locations from iCal files.
