In woorank, dubin core error is found. It writes set of standard metadata elements are missing like type, source, relation, coverage, creator, publisher, date, format and many more. Is this important in ranking, if it is then please explains each meta.
If you define these , it is easy to understand. A standard meta tag contain all (author ,time, date etc). These are helpful for visitors/rankings. Meta tags plays an important for website. Google see meta description where yahoo see meta keywords etc
All these elements are essential for on-site optimization, and you want to make your site friendly both for users and search engines, then it's necessary to fix all these issues. I know there are some onpage optimization software packages (website auditor etc.) which will give you detailed and personalized advice on how each on-page issue can be fixed.

Besides all meta you suggested in the given link https://support.google.com/webmasters/answer/79812?hl=en, dublin core suggest some more meta like type, source, relation, author, publisher, date, format, etc. are also important or not?
It is not important .You could check the top websites on dublin core where you find that these sites are also not using lots of tags.If you think it's important then you can use all these tags,it's not give any impression in SEO.
Hello, Although a lot of weight used to be given to meta tags by the search engines, on the whole they are now unimportant elements of a website. Instead of using meta tags to determine what a webpage is about, the search engines now focus on other tags and the content of a webpage (their intelligence has greatly increased over the years). The keyword meta tag in particular is not used at all by the search engines in determining a web page’s authority. Have a nice day !!! Thanks !
Hello Lasse, according to you, it is now unimportant tags and focus on other tags. Can you describe me which other tags are good for SERP.
