[bioontology-support] [BioPortal] Feedback from kkochut

hi Krys,

As we discussed offline, we know we can't upload ontologies above a certain size (not yet quantified, but for sure above 2 GB).

Let's continue to discuss a strategy for troubleshooting this off-line—I think a test with BiblioPortal may be useful.

I created a summary page for a new ontology submission without any problems. It is a Protein Kinase Ontology (PROKINO). However, I am having problems uploading the OWL file. The ontology includes many individuals and the serialized OWL file is quite large (about 2.9 GB).

After failing a couple of times while using the Web browser-based submission form, I tried a command line on a Linux system using the cURL command. It also failed with the following result:

413 Request Entity Too Large

413 Request Entity Too Large


I was executing a POST request (using curl) on the resource /ontologies/PROKINO/submissions, using the -T option and I specified the "chunked" encoding. However, the upload failed after uploading nearly 37% of the file.
Is there an alternative way to upload this ontology?
Thank you.
