Hello Georges Thanks for the paper, it is interesting. Of course I support the proposal for a new geospatial track in ApacheCon 2018 and hope to participate too.
Section 4.2 (Cloud computing for EO data) mentions the lack of common API for interacting with the clouds. The section enumerates authentication, billing, etc. as examples of services for which there is no common API, but maybe we could add map projections, coverages access methods, etc. to that list if we envision that some companies may offer clouds specialized in geospatial data? This section cites web services (WMS, WCS, WPS) as a common API, but for simple processes like a map projection, the encoding and decoding parts can count for 90% of the total execution time. It is possible to avoid that cost in some situations by standardizing an API at the programming language level, in addition to web APIs. Inconvenient is that the way to transfer data become more language-dependent. It would be possible to produce a proof of concept in OGC test bed 14 as a side-effect of proposed topic on map projection validations. Note: I think there is a minor typo in the link to "Big Data from Space 2106 conference"; I presume the intended year was "2016"?
