I’m thinking of turning this feature on, whatever it is or however it works, but, out of curiosity:
I would often like to search for events. What is happening in the community, around town, within local driving distance.
In general, in the past, searching for any kind of event with any available search engine would often result in finding a web page about something that happened already, like last month or last year. Often quite useless.
Also, some numbers on some web page could be almost anything. How in the world could YaCy possibly distinguish a “Start date” from an “End date”, or recognize any kind of date from other numerical data on a website?
My assumption is that this could only work if the dates on the page are marked up with XML or JSON or some such thing. There are also, perhaps a dozen different possible date formats that could exist in almost any context.
If I wanted to create a web page about an event, how would I best mark up the web page or designate the start date of an event so that YaCy could recognize it?
This seems like a very interesting and useful feature, but I would like to know how it works. What are the limitations? What is possible?
What the heck is itemprop?
A form of “microdata”, apparently? How many web-page creators actually use this kind of markup?
Does the date have to be in ISO 8601 format for YaCy to recognize it or will it store anything appearing within a date meta field as shown above?
