[jira] [Issue Comment Edited] (STANBOL-433) Loading large ontology using Java API gives out-of-memory error

    [ https://issues.apache.org/jira/browse/STANBOL-433?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13171501#comment-13171501 ]

This was loading an ontology from a file of around 200MB; the file was in fact an RDF SKOS thesaurus.  In fact we'd like to be able to load files larger than this (the vocabulary is currently split into three files - combining these would give a file of around 500MB).

The ontology was being added via the Space.addOntology(OntologyInputSource) method.

We tried loading this in a VM of around 3GB.
