How to write Queries?

Odet supports querying of the underlying data & creating Specs using them

Spec comprises of 3 parts

1. Collection
2. Filter
3. Rule

Eg. Collection: Repo Filter: IN(tags, 'level 1') Rule: ==(language, 'Ruby')

Collection

• Set of entities on which the Rule will be applied. Repo means "All Repos"
• You can filter collections using Filter to get a subset of Collection

Filter

• Filter is applied on the Collection to give you the set of elements on which the Rule will be evaluated. In the above example, the set becomes All Repos which have the tag 'level 1' applied to them.

Rule

• A Rule has three parts, an operator and two operands. Here operator being == (equality) which checks if the github_language value matches with Ruby or not.
• When you apply the Rule on the Above set, it evaluates for each Repo and returns success/failure.
