Re: SPARQL endpoint [Was: Dataset not applied to queries]
hi, yo it's an older version.. we've already upgraded a couple of versions as well and are integrating the sparql endpoint in our own rya fork.. there was hardly any reaction to the fist version, so i'm happy that the discussion is starting again. i'll make sure to commit our current version during the next days and you can have a look at it. krj *Jürgen Jakobitsch* Senior Technical Consultant Semantic Web Company GmbH EU: +43-14021235 <+43%201%204021235> US: (415) 800-3776 Mobile: +43-676-6212710 <+43%20676%206212710> https://www.poolparty.biz https://www.semantic-web.com *Download E-Book*: Introducing Semantic AI <https://www.poolparty.biz/machine-learning-meets-semantics/> Am Mi., 5.

Re: SPARQL endpoint [Was: Dataset not applied to queries]
no, i didn't include that parameter.. usually this parameter is anyway included in the SPARQL query itself as FROM or FROM NAMED. mind that depending on the situation you might have to rewrite the query.. also mind that there are some application specifics involved, since we also have DEFAULT keyword in SPARQL and finally also mind that the evaluation strategy (the actual SPARQL engine here) must make use of the graph constraint, which i think isn't done at the moment krj *Jürgen Jakobitsch* Senior Technical Consultant Semantic Web Company GmbH EU: +43-14021235 <+43%201%204021235> US: (415) 800-3776 Mobile: +43-676-6212710 <+43%20676%206212710> https://www.poolparty.biz https://www.semantic-web.com *Download E-Book*: Introducing Semantic AI <https://www.poolparty.biz/machine-learning-meets-semantics/> Am Mi., 5.

Re: SPARQL endpoint [Was: Dataset not applied to queries]
hi there, we've implemented the whole sparql endpoint anew. some of the features from the old endpoint are still missing, but i think they need some re-engineering anyway, like send a user as a url paramter is not exactly a good idea.. i'm including a mail from i wrote from earlier this year (around april/may) hi, as mentioned in previous mails, we've setup a first draft of the proposed upgrade of rya's sparql endpoint.. again note, that we've setup a small debug/demo maven project using a sesame memory store to demonstrate the proposed changes. if the proposed upgrade of the sparql endpoint is welcome we would incorporate this with existing rya code to include all required rya features. features: 1. full support for content-negotiation (essential within the linkeddata/semantic web realm) 2. SPARQL Service Description 3. more HTTP Status Codes (202 accepted, 400 bad request, 200 ok) 4. all RDF serialization formats available natively from sesame 5. customizable web endpoint (via a sesame MAVWriter (ModelAndView) + JSPs + Styles) 6. valid XHTML for the endpoint 7. valid XHTML+RDFa in a browser for construct queries 8. a future rdf4j upgrade will not seriously affect the whole endpoint the project is very easy to build and you can checkout all features on your local machine easily (examples are provided). the maven build will include a tomcat hosting this sample endpoint, descriptions and code can be found here: https://github.com/jj-semantic-web-com/rya-sparql-endpoint any feedback, pointers, comments and wishes are highly welcome! related JIRA task: https://issues.apache.org/jira/browse/RYA-477 kr jürgen *Jürgen Jakobitsch* Senior Technical Consultant Semantic Web Company GmbH EU: +43-14021235 <+43%201%204021235> US: (415) 800-3776 Mobile: +43-676-6212710 <+43%20676%206212710> https://www.poolparty.biz https://www.semantic-web.com *Download E-Book*: Introducing Semantic AI <https://www.poolparty.biz/machine-learning-meets-semantics/> Am Mi., 5.

Re: Docker Deployment
hi there, we at semantic web company, have a running installation on DC/OS using docker images, orchestrated via mesosphere marathon. that's certainly possible and runs easily, but you need to specify which orchestration you're using to get your DNS resolutions to zk, hdfs and accumulo right, in case you want to deploy all components in more than one single docker image krj *Jürgen Jakobitsch* Senior Technical Consultant Semantic Web Company GmbH EU: +43-14021235 <+43%201%204021235> US: (415) 800-3776 Mobile: +43-676-6212710 <+43%20676%206212710> https://www.poolparty.biz https://www.semantic-web.com *Download E-Book*: Introducing Semantic AI <https://www.poolparty.biz/machine-learning-meets-semantics/> Am Fr., 26.

Re: October podling report draft - please comment
i'd support mentioning the folks from semantic web company :-) (it's certainly not going to be drive-by as well) we will be using rya during the next three years intensively for one of our research projects (h2020 => logistar) we just setup a fork on our official github. using this we will commit step by step a lot of issues that we've already tested on our local installations (on different nodes and on DC/OS) including accumulo/hdfs/libthrift version upgrades and a new shiny sparqlendpoint conforming to all standards. we do this on a step by step basis now, to be able to create meaningful and contained pull requests.. krj *Jürgen Jakobitsch* Senior Technical Consultant Semantic Web Company GmbH EU: +43-14021235 <+43%201%204021235> US: (415) 800-3776 Mobile: +43-676-6212710 <+43%20676%206212710> https://www.poolparty.biz https://www.semantic-web.com *Download E-Book*: Introducing Semantic AI <https://www.poolparty.biz/machine-learning-meets-semantics/> Am Mo., 1.

note: we (semantic web company) will be issuing a pull request very soon
with respect to updating those dependencies.
we did a very successfull test with:
1. rya 4.0.0-snapshot (the rdf4j version)
2. accumulo 1.8.1
3. hdfs 2.9.0
4. the proposed sparql endpoint upgrade [1] [2] [3]

Re: can't create a Rya Accumulo repo in Vagrant Example of incubator-rya
hi bob, don't know about vagrant environment but rya is built against specific versions of hadoop and accumulo, you cannot just change them, without hitting some issues. note: i'm using rya on DC/OS (dcos.io) with hdfs 2.9.0 and accumulo 1.8.1 and had to change some code snippets, especially with respect to libthrift. krj *Jürgen Jakobitsch* Innovation Director Semantic Web Company GmbH EU: +43-14021235 <+43%201%204021235> US: (415) 800-3776 Mobile: +43-676-6212710 <+43%20676%206212710> https://www.poolparty.biz https://www.semantic-web.com *Download now <https://www.poolparty.biz/wp-content/uploads/2017/08/IDC_Paper_How_Semantic_Technologies_Steer_Cognitive_Applications.pdf> **IDC White Paper* *Get certified! <https://www.poolparty.biz/academy/> **PoolParty Academy* *PoolParty selected as a KMWorld Trend-Setting Product for 2017* PERSONAL INFORMATION | web : http://www.turnguard.com | foaf : http://www.turnguard.com/turnguard | g+: https://plus.google.com/111233759991616358206/posts | skype : jakobitsch-punkt | xmlns:tg = "http://www.turnguard.com/turnguard#; | blockchain : https://onename.com/turnguard 2018-05-15 21:22 GMT+02:00 <b...@bobdc.com>: > I > am trying to use the Rya Vagrant Example shown at > https://github.com/apache/incubator-rya/tree/master/ > extras/vagrantExample/src/main/vagrant. > After updating the ACCUMULO_VERSION, HADOOP_VERSION, and > RYA_EXAMPLE_VERSION values in Vagrantfile (the old values referenced > versions that were no longer available) , I got incubatory-rya > installed, and all of the verification steps worked.

Re: 4.x branch for RDF4j updates.
hi, my 2 cents: since this might look a little easier than it is in reality i'd give my +1 to a feature branch (4.0.0). => rather take a little more time and upgrade more deps and test thoroughly.. note that you might scare away NEW installations with old dependencies.. (when i first installed i'd thought i'd rather upgrade deps myself than installing a five year old HDFS) notes: 1. for us at semantic-web.com it would be really important to have the latest rdf4j version (note: we're upgrading to 2.3. due to some critical rdf4j 2.2* bug in our product) 2. there won't be any backwards compatibility with respect to the requirement of having to install accumulo/hdfs, mongo anew.. (note: we were testing our installation with accumulo 1.8.1 + hadoop 2.9.5 on DC/OS and with a relatively new version of mongo on premise). (note: later accumulo versions depend on a newer libthrift version, which requires a knowledgeable person to take a look) kr jürgen [1] https://semver.org/ *Jürgen Jakobitsch* Innovation Director Semantic Web Company GmbH EU: +43-14021235 <+43%201%204021235> US: (415) 800-3776 Mobile: +43-676-6212710 <+43%20676%206212710> https://www.poolparty.biz https://www.semantic-web.com *Download now <https://www.poolparty.biz/wp-content/uploads/2017/08/IDC_Paper_How_Semantic_Technologies_Steer_Cognitive_Applications.pdf> **IDC White Paper* *Get certified! <https://www.poolparty.biz/academy/> **PoolParty Academy* *PoolParty selected as a KMWorld Trend-Setting Product for 2017* PERSONAL INFORMATION | web : http://www.turnguard.com | foaf : http://www.turnguard.com/turnguard | g+: https://plus.google.com/111233759991616358206/posts | skype : jakobitsch-punkt | xmlns:tg = "http://www.turnguard.com/turnguard#; | blockchain : https://onename.com/turnguard 2018-04-09 19:55 GMT+02:00 Jeff Dasch <hcs...@gmail.com>: > The simplest thing for the community is to have a single branch of > development that is being supported/maintained.
