probe-it 2 lighter version b/c relies upon visko. next version might be javascript. leaving browser becomes awkward.

Twice as many NodeSets as Information? We'd expect 1:1 But more NodeSets are ok because we just have more justifications for the same Informations.

UTEP's experiences: different files assert different hasURLs on the same instance URI of information these get accumulated when aggregating them together. 1 info with many hasURLs BAD.


IN how many ways ARE we justifying the same Information?


Tim is using multiple antecedents

hasURL should be inverse functional?


TODO: cite example queries on UTEP into Layer page for instance analysis.


90 Inference Engines! most of them are subsequent versions of a larger grouping (hashing the curl, hashing the converter - should be binned)

Nick: if you are naming the new engine, are you naming a new rule? UTEP is making a lot more inferencerules contextualizeing the RULE according to the InferenceEngine. reusing a lot of SAW (Leo) saw:Algorithm => InferenceRule. different b/c in different namespace. each inferenceengine has unique set of inferencerules. Tim: Where do the namespaces get used? Every workflow has it's own namespace. Tim: Can you escape your namespace? Nick: No. Doubt you can reuse. Cannot import a SAW, only another ontology.



  • different wgets - what (w)gives?
    • Tim's wget is different from Jitin's wget params.
    • Tim's wget params do not work for Jitin's web directory URLs
    • anyone interested in taking a look?
  • human attribution on InferenceStep (provenir, hartig, and OPM -- but not PML)
    • revisiting all of the information-level "dots" and adding citations to the people involved in those steps.
  • opendap?
    • Leo was there , Jitin and Nick were not.
