Document view URIs

View URIs are very similar to dataset URIs. View URIs begin with "view:" instead of "dataset:". The URI patterns are the same as dataset URI patterns for all options.

In addition to the dataset URI options, view URIs can have data constraints expressed as "<field>=<constraint>" in the query section of the URI. Record and partition field names will be checked for constraints on those fields.

A constraint can be:
1. A range, expressed as an interval of two comma-separated endpoints and inclusive or exclusive bound characters ("(", ")" = exclusive; "[", "]" = inclusive). An empty string is used for both positive and negative infinity. Examples: "(,3]" = less than or equal to 3, "[10,20]" = between 10 and 20, inclusive.
2. A list of comma-separated values. Example: "id=34,35" or "color=green"
3. Empty, which means that there must be a value (non-null). Example: "id=" means any id
