Hi Dave,
Good question. Currently, there are no plans for GeoMesa to be free of
GeoTools. At the minute, GeoTools and GeoServer are two of the best
projects for handling geospatial processing and serving up the results
via OGC access patterns. It is inconvenient that their licenses aren't
more business friendly. I'd point out that several of these projects
were in existence before ASF license version 1.1.;)
In terms of integrations of GeoMesa and Apache projects, in many cases
(such as Storm or Kafka), I think it might make more sense for GeoMesa
to depend on the Apache project or for there to be a third-party project
which depends on both (for example with NiFi). Overall, I'd love to see
better licensing so that dependencies can go either direction. I spend
more time than I care to dealing with legal details like this...
For other LocationTech projects, I'd point out that only a few use
GeoTools. For instance, Spatial4J is used by Apache Lucene. Overall,
the Eclipse Foundation (and LocationTech by extension) hosts projects
which have business-friendly licenses.
Anyhow, I hope that helps clarify things a bit.
Cheers,
Jim

RYA-179 is corrections to Rya source file license headers.
Jim, do you know when GeoMesa plans to be completely free of GeoTools ?
Clearly Geotools is an obstacle for Apache projects to use LocationTech
projects, or at least GeoMesa.
Or is there another path forward for GeoMesa?

Could we revive the indexer profile again?
(tl;dr: Yes. Mentors: Please correct us if we're wrong)
This might be a solution. I found a couple similar cases with Apache
projects and discussions related to those cases.
Apache Flink integrated with Amazon Kinesis [1] and [2]. Note that Kinesis
is an optional profile, and it's well documented in the POM why it's
optional.
(Note that NiFi got around this by using Amazon's SDK for Java [3], which
is purely Apache 2.0)
Spark uses optional profiles to build artifacts based on LGPL
dependencies. Spark has to built by the user to use netlib [4][5], Ganglia
[6], or Kinesis [6].
I think a profile will work, but I'd like to see it well documented (both
in the POM and manual) so that we never accidentally create a release with
these artifacts.
I was going to open a separate ticket to implement this, but I think it's
good to track all of this effort under RYA-177.

Great find Aaron!
The ESRI library is quite comparable!
Rya via Geomesa are using *JTS Topology Suite (*JTS): (the javadocs at
vividsolutions seems to be 404 )
http://tsusiatsoftware.net/jts/javadoc/com/vividsolutions/jts/geom/
Geometry.html
Far from a drop-in replacement, but a path forward:
http://esri.github.io/geometry-api-java/javadoc/
Interesting, ESRI has Shape file support, but no GML, the opposite of
JTS!

Yeah, that sounds possible. I don't like the idea of having to maintain
another build/ci/release process, though.
More importantly, we'd also have to modify our GeoIndexer interface [1]
to
something Apache Friendly. It looks like Ersi puts out an Apache 2.0
library [2].

Hi Aaron,
Thanks, wasn't finding that list quickly...
It sounds like the GeoMesa/GeoTools usage might fall under this Q/A:
http://www.apache.org/legal/resolved.html#optional.
Thoughts?

Hi David,
A number of the geo-dependencies are likely from the geo-indexing
(which
uses GeoMesa (Apache 2.0) which uses GeoTools and JTS).
Are there options to make the geoindexing a profile, provide the
source,
and not provide artifacts for that code at Apache?
Also, is there a list of approved licenses for Apache projects
dependencies?
Cheers,
Jim
