Keyword validation differs from http://project-open-data.github.io/schema/

[willpugh]

Both DCAT + http://project-open-data.github.io/schema/ have the "keyword" property written as being singular.

However, the validator seems to want the "keyword" property be plural, e.g. "keywords"

Created a pull request [Issue #6] that solves this.
