Trees in Mongodb, my notebook with Gene Ontology
In the current post I've loaded the Gene Ontology into MongoDB and played with the tree structure of the database:
Loading GeneOntology into MongoDB
First, download GO as RDF at http://archive.geneontology.org/latest-termdb/go_daily-termdb.rdf-xml.gz and transform it with my XSLT stylesheet go2mongo.xsl (available here):<?xml version='1.0' encoding="UTF-8" ?>

Playing with the GeneOntology Tree
I'm going to look if a go-term is a descendant of one another. First, let's define two useful javascript recursive functions looking for the parent(s) of a given node threw the property is_a.var goNodeIsA= function (childNode, parentId) {
if (childNode == null) {
return false;
}
if (childNode._id == parentId) {
return true;
}
if (!childNode.is_a) {
return false;
}
for (var i = 0; i < childNode.is_a.length; ++i) {
if (goNodeIsA(childNode.is_a[i].fetch(), parentId))
{
return true;
}
}
return false;
}
if (childNode == null) {
return false;
}
if (childNode._id == parentId) {
return true;
}
if (!childNode.is_a) {
return false;
}
for (var i = 0; i < childNode.is_a.length; ++i) {
if (goNodeIsA(childNode.is_a[i].fetch(), parentId))
{
return true;
}
}
return false;
}
var goIsA=function (childId, parentId)
{
return goNodeIsA(db.go.findOne({_id:childId}), parentId);
}
{
return goNodeIsA(db.go.findOne({_id:childId}), parentId);
}
Now, let's find if GO:0003723 (RNA binding) is a descendant of GO:0005488 (binding) ?
> goIsA("GO:0003723","GO:0005488");
true
true
And is GO:0003723 (RNA binding) is a descendant of GO:0050355 (triphosphatase activity) ?
> goIsA("GO:0003723","GO:0050355");
false
false
Loop over all the GO terms and find the descendants of GO:0050355 (triphosphatase activity):
> db.go.find({},{name:1,is_a:1}).forEach(function(term) { if(goIsA(term._id,'GO:0005488')) printjson(term); })
