Hi All,
In light of recent developments, I am playing catch up and
restructuring our SW dev environment and workflows ( we started with
jess, jena, sesame, etc. Long ride since ).
There are two elements here regarding Virtuoso:
* Dev/Staging/Prod generic purpose machines on the cloud with
appropriate workflows ( almost done, will use AMIs )
* Local developer dev env / Individual sandbox ( to test high
throughput/unstable scripts against local data, for example )
For the latter point, I would love to hear your suggestions ( OpenLink
and ecosystem ):
1. What is the simplest VOS distribution that can be used for personal
Developer machines?
( w/o the virtual database engine, I know that's another story )
* Macs, Windows and Linux.
[Hugh] Linux , Mac, Windows would be the order of preference, as Linux is
the easiest to build on as ever, followed by Mac which is "a unix" in
disguise although a bit tricker due to universal binary requirements, and
windows is the hardest to build on, although not impossible with all the
tools in place, but we provide a VOS windows zip file containing prebuilt
binaries for each release. Would you be seeking to install VOS on each
personal machine or would their be a local central server that would be
used. Also do you already have the hardware and OS'es in place or is this
still to be decided ?
OSs are heterogeneous for now.
Each dev has its own machine.
OK. So I take it that the suggestion would be Virtuoso Opensource as
indicated in the website, and I understand the build order ( see,
that's an important advice if we are going to be doing this often ).
Aldo,
When dealing with an EC2 AMI the Open Source Edition has little or no value.
The EC2 AMI is basically an unrestricted commercial edition of Virtuoso.
Far more functionality etc..
* I want this to be drop dead easy so I can setup VOS instance on
everyone's machine and have them running SPARQL via hosted PHP, etc in
seconds.
"Seconds" with PHP runtime hosting is what you get via an EC2 AMI or the
normal Commercial Edition installer. Of course you can build VOS also,
but time is the scarce resource we hone into re. the packaging of
Virtuoso along commercial and open source boundaries (bottom-line).
[Hugh] This is possible once you have your binaries built and a working
installation, as you can then us a single command to start the server on any
similar machine.
Commercial Edition.
Kingsley
Yes.
2. What datasets would you preload?
** I imagine you have different sets for different purposes... I need
to execute, at least:
*** SPARQL-BI to feed visual analytics ( think charts )
*** Complex SPARQL queries for browsing ( think longwell/facets +
tabulator/nav ), with aggregates
** Therefore, data must be rich in cardinality, multidimensional and
user-understandable ( products, people, places, etc ).
** It would be great to use "standard" sets whenever possible so
results could have some meaning across company borders
** I am talking normal machines here ( think your notebook ).
[Hugh] I am not really sure what you mean here as you would typically start
with an empty database, thus no datasets would be created, although I do
think same basic Virtuoso RDF data does get created. All the SPARQL variants
(SPARQL, SPARUL, SPASQL, SPARQL-BI) would be available by default. Are their
any specific datasets you would want to be preloaded ?
Loading the data is simple... I was basically wondering if you had any
datasets *of choice* to leverage and test Virtuoso's power ( the
different flavors of SPARQL it provides ).
For example, Northwind?
But don't worry, this is just an open question, just like the above. I
can load any data I want, of course.
I'm mostly searching for insider recommendations and best practices. I
don't like to reinvent the wheel when possible, and like to hear what
others are up to.
Thanks for your time Hugh ;)
Best Regards
Hugh Williams

Best,

I don't really know this ecosystem well enough yet, but I do know/hope
that you will soon be overloaded with new developers so I will try to
create self contained questions that can be later used as reference.
Thanks,
A
