[BP] EO-QB meets BP

Dear  BP editors,
This relates to eo-qb issue-107 and issue-100.

I have revised EO-QB to make reference to its application of best practices, you might like to have a look. http://w3c.github.io/sdw/eo-qb/

As I did it, I spotted  a few places where BP might like to reference EO-QB as  examples.

1.  Balancing quality and cost
BP Encoding spatial data https://www.w3.org/TR/sdw-bp/#semantic-thing needs an example for "Balancing quality and cost." "For example, if using a Linked Data approach, one option is to keep all data in a triple store; but hybrid approaches are also possible, " ... This EO-QB could be the missing example,  Say...

In EO-QB  satellite imagery metadata is stored in a triple store but observational data is stored in HDF5  and served through DGGS and query processing middleware that materializes RDF triples only in response to a SPARQL query for them.

2.BP change over time
"Best Practice 6: Describe properties that change over time" I suppose EO-QB is an example of approach 3 "capturing a time-series of data values within an attribute of the spatial thing." Although in eoqb he spatial thing itself (earth surface) is never really mentioned...  I suggest "EO-QB" should be added to the list of includings in the following (although it is not quite a standard itself, but it uses the RDF datacube standard to do it)  "Standard data encodings are available for time-series data, including: [TIMESERIESML<http://w3c.github.io/sdw/bp/#bib-TIMESERIESML>] for [GML<http://w3c.github.io/sdw/bp/#bib-GML>], plus [COVERAGE-JSON<http://w3c.github.io/sdw/bp/#bib-COVERAGE-JSON>] and [SENSORTHINGS<http://w3c.github.io/sdw/bp/#bib-SENSORTHINGS>] for JSON."

3. section 6
"Coverages: describing properties that vary with location (and time)" should reference EO-QB and COV-JSON.
Note that COV_JSON uses the domain/range/range metadata  model explicitly whereas in EO-QB this model is  obscured by the primary  conceptualisation as  a  3-dimensional Data Cube.

4. crossreferencing to UCR

BP doc should crossreference req https://www.w3.org/TR/sdw-ucr/#CoverageTemporalExtent  from
