René's URL Explorer Experiment

{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"Generalized mechanism for data provenance","articleBody":"There should be an interface `Sourced` with API `getSource()`, that returns a descriptor of all data objects involved in the creation of the `Object` in question. Intuitively, `Module` is a good candidate for this descriptor. But we must be very careful about weak versus strong references. \n\nWe want a provenance post processor which, for each output that implements this interface, attaches all inputs via `setSource(...)`. \n\nThis allows images to know how were they were generated and even reproduce that workflow again in some cases. ImageJ-OMERO would use this to know which OMERO datasets are relevant to newly created images. But the applications are numerous and varied. \n","author":{"url":"https://github.com/awalter17","@type":"Person","name":"awalter17"},"datePublished":"2016-02-17T18:22:16.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/227/scijava-common/issues/227"}
