This page describes the status of the public Solr index for the GO. This index will replace some of the query functionality for GOOSE as well as become the new backend for AmiGO 2 and other services. A preview server is now active at http://golr.berkeleybop.org.
The preview server at http://golr.berkeleybop.org is currently in alpha.
Some preview documentation is at http://api.berkeleybop.org .
Feel free to use it as you will and start to write for it. As this is still a little early, we are only loading the GO, CL, ECO, and taxslim, as well as non-IEA annotations from the GAFs. Please see the AmiGO_Labs caveats, as well as the downtime information on this page.
We are now loading properly from owltools.
We have looked at nginx as a reverse proxy for speed and to prevent unauthorized access to non-select URLs on the Solr server, and found it to be good.
The GOlr server is now active at http://golr.berkeleybop.org (nginx front on stove).
We now also have http://amigo2.berkeleybop.org working on stove and backed by golr.berkeleybop.org.
We are now on Solr 3.6. At some point we'd like to get on 4.x for some improvements including pivot tables.
We are currently working towards a flexible schema as defined in the owltools code. As we roll it out for the AmiGO backend and as a replacement for common GOOSE queries, we expect to find holes in the schema, documented below.
Currently, the index is entirely populated by through an owltools command line program, using YAML files for configuration. The Solr schema.xml generation looks like:
./OWLTools-Runner/bin/owltools --solr-config /home/sjcarbon/local/src/svn/owltools/OWLTools-Solr/src/main/resources/ont-config.yaml /home/sjcarbon/local/src/svn/owltools/OWLTools-Solr/src/main/resources/bio-config.yaml /home/sjcarbon/local/src/svn/owltools/OWLTools-Solr/src/main/resources/ann-config.yaml /home/sjcarbon/local/src/svn/owltools/OWLTools-Solr/src/main/resources/ann_ev_agg-config.yaml --solr-schema-dump
With the actual population along the lines of:
owltools http://purl.obolibrary.org/obo/go.owl http://purl.obolibrary.org/obo/ncbitaxon/subsets/taxslim.owl http://purl.obolibrary.org/obo/cl.owl http://purl.obolibrary.org/obo/eco.owl --merge-support-ontologies --reasoner elk --solr-url http://localhost:8080/solr/ --solr-purge --solr-config /home/bbop/local/src/svn/owltools/OWLTools-Solr/src/main/resources/ont-config.yaml --solr-load-ontology --solr-load-panther /optional/wherever --solr-load-gafs /srv/tmp/gene_association.mgi
For the sake of completeness, a development load that we often run looks like:
./OWLTools-Runner/bin/owltools http://purl.obolibrary.org/obo/go.owl http://purl.obolibrary.org/obo/ncbitaxon/subsets/taxslim.owl http://purl.obolibrary.org/obo/cl.owl http://purl.obolibrary.org/obo/eco.owl --merge-support-ontologies --reasoner elk --solr-url http://localhost:8080/solr/ --solr-purge --solr-config /home/sjcarbon/local/src/svn/owltools/OWLTools-Solr/src/main/resources/ont-config.yaml --solr-load-ontology --solr-load-panther ~/tmp/tree --solr-load-gafs http://www.geneontology.org/gene-associations/gene_association.GeneDB_Spombe.gz http://www.geneontology.org/gene-associations/gene_association.dictyBase.gz
Rewriting old GOOSE query examples for the new GOlr Schema
Example queries on the wiki.
- Some old queries require the use of Solr facets and some modification of code Seth has written to present simpler results queries (i.e. the facet results are not displayed).
- Note: hierarchical queries that 'combine' facet queries can be handled by the facet.pivot functionality that is available in Solr 4. In the meantime, we'll see if we can devise a work-around.
Current holes in the GOlr schema
- None listed at this time...
Rebuilds start at 10pm PDT (6am BST; 5pm NZST), so there may be some data gaps in there.
At the time of this writing, this process is taking a few hours.
Local installation (data and schema development)
These instructions are intended to illustrate how to install the GOlr server software for AmiGO 2 on a Ubuntu 12.04 LTS Desktop. With careful reading, these instructions should be generalizable to other cases.
The following packages are required:
Also, you will need a version of Maven 3 (mvn) to use and build OWLTools if you are trying to load data. It is a fairly simple process to download it and make sure that it is in your path.
First, we need to download and build OWLTools--it contains the loader code that GO uses for ontology and GAF files, as well as the tools to generate a new Solr schema from AmiGO 2 YAML config files. The code should be self-sufficient and easy to build on a machine with an internet connection.
Before we start, we need to get Maven 3 working.
Now we can move on to getting the OWLTools source code.
cd ~/local/src/svn svn checkout http://owltools.googlecode.com/svn/trunk/ owltools-read-only
cd WHEREVER/owltools/OWLTools-Parent/ && mvn clean package
Or, without unit tests (much quicker):
cd WHEREVER/owltools/OWLTools-Parent/ && mvn clean package -DskipTests
The owltools binary that we'll be referring to later will be in:
This should either be in your path or you will have to make this path explicit whenever you use owltools.
Getting the GO Solr schema (GOlr) working
While we have Jetty installed from the repos, we have our own Solr (3.6) in the GOlr repo as the one that comes with Ubuntu is ancient. While we install/handle our Jetty/Solr setup with the golr.el script found in the GOlr repo, you may find it easier to just look at the script and copy its actions unless you're really into Emacs.
The most important part is using the correct schema.xml (derived from YAML files using OWLTools, but that's another story). The solrconfig.xml is also there and might be useful.
There are two options for this.
Generating the schema from AmiGO 2 (geneontology repo)
This software contains the GO-specific things that BBOP JS does not support--the client (web server) code for AmiGO 2. For the sake of convenience (and using a similar directory layout to the developers), we'll get it like:
mkdir -p ~/local/src/svn cd ~/local/src/svn svn co https://geneontology.svn.sourceforge.net/svnroot/geneontology/AmiGO/trunk geneontology/AmiGO/trunk
Using the premade GOlrs schema (geneontology repo)
Server code and utilities for handling the GO Solr schema.
svn co https://geneontology.svn.sourceforge.net/svnroot/geneontology/golr geneontology/golr
This is just utility code and the GO data schema, no building is necessary.
Loading the data
As an example, we will load four ontologies useful to GO right now and a single GAF file for annotations onto the localhost Solr instance. Please note the WHEREVER, the other resources are on the web.

More memory is always welcome, but less is probably sufficient. The panther section
--solr-load-panther ~/tmp/PANTHER7.2_HMM_classifications ~/tmp/tree
is optional and experimental--it can be left out entirely.
