Greetings!
We are happy to announce that Hyrax 1.15.1 is released. This version is (mostly) a bug-fix release for Hyrax 1.15.0. See https://www.opendap.org/software/hyrax/1.15.1.
The MDS (Metadata Store) was installed incorrectly from the CentOS rpm packages; fixed.
This version of the server also includes the first developer (i.e., source) release of the BALTO brokering code and an alpha version of JSON-LD support for BALTO/Hyrax.
Included, in addition to the RPM packages for CentOS 6 and 7 and source tar balls, are Docker images for the server both with and without the ncWMS service. See https://hub.docker.com/u/opendap/ or the link on the Hyrax release page.
Specific tickets fixed for 1.15.1

Hi, James!
Thank you for tips on build_dmrpp.
I made a tiny patch for help message of build_dmrpp tool on GitHub.
However, I could not generate DMR++ map with -r option.
I think the -r option is supposed to write an XML from HDF5 file
but the tool failed with an obscure error:
[ec2-user@ip-172-31-18-183 hyrax]$ ./build/bin/build_dmrpp -f CER_SYN1deg-1Hour_Terra-Aqua-MODIS_Edition4A_407406.20180601.nc4 -r test.dmrpp
Error: ^{
I built Hyrax from the source for EC2.
I think my Hyrax is working with http_d_int.h5.dmrpp
after I whitelist cloudydap s3 in gateway module.
Do you have any clue on how to debug / make -r option work?

Hi, James!
Do you have any detailed instruction / documentation on running dmrpp_module with S3?
No. If you just have one file, use EBS. But you raise a good point!! We should have docs for this.
Here’s an outline - it’s really not hard.
In the DMR++ code there’s a tool called ./build_dmrpp that is used to seed the Metadata Store with the DMR++ needed by the handler to read from the granule when it’s in S3. The DMR++ is added to the MDS using a certain URL pathname and that URL path is used to access the DMR++ by the server. The DMR++ has the S3 URL of the granule embedded in it.
It’s pretty much the wild west at this point. But I think you can get it working. Let me know how it goes; we can use your experiences and ideas to make it simpler for less technical users.
Thanks,
James
