What will Obsidian read from the Metadata?

I am new (2 weeks) to Obsidian. I came from Zettlr.

Zettlr reads the title and keywords/tags from the metadata. I have learned that Obsidian also reads tags from the metadata. But apart from tags, are there any other things that is recognizable by Obsidian? Or Metadata is just for my personal reference?

Thanks in advance.
