2 Provenance Origin or source from which something comes, history of ownership, intention for use, who generated something, what is generated for, manner of manufacture, sense of place and time of manufacture, production or discovery, documented in detail sufficient to allow reproducibility Knowledge provenance; enrich with ontologies and ontology-aware tools

PML Provenance It is about provenance concepts URI for identifying and addressing Declarative metadata Taxonomy #info1 a pmlp:Information; pmlp:hasRawString “(type TonysSpecialty SHELLFISH)” ; pmlp:hasLanguage ; pmlp:hasFormat ; pmlp:hasPrettyString “Tonys’ Specialty is ShellFish” ; pmlp:hasURL “ ”.

Science and data Science is built on verifiability and reproducibility As more layers are inserted between the scientists and the origin data, or when the data is out of the usual realm of familiarity –Trust must be established –Sources must be verifiable and proved –Explanations must be given and connected 6

8 Example Use Cases What was the cloud cover and atmospheric seeing conditions during the local morning of September 19, 2008 at MLSO? Find all good images on September 21, Why are the Quicklook images from September 21, 2008, 1900UT missing? Why does this image look bad?

Implementation of PML model Retrospective – scraping the un-related sources –Needed to gain confidence and trust from the users –PML generated after the fact (can re- generate) which is very good at the development stage Proactive – PML on the fly as data passes through the pipeline –Preferred but only when model is mature 18
