SPCDIS User Annotation Use Case 1

Printer-friendly version

Short description:

In this use case, a user asks about a problem/event with one image, and gets a reply relating the problem/event to MLSO-generated data products used to generate that image.


A user Alice is looking at intensity pictures for 10d242, and notices the entry 20100830.223717.chp.hsc.fts is assigned an ‘UGLY’ rating. Curious about why this is, Alice submits the following request: “Are there any known events which caused this image to be assigned an ‘UGLY’ rating?” Following this, a link is made from Alice’s clarification request to the data product.

Next, an alternate user Bob (affiliated with ACOS) replies through establishing a link from a piece of data representing the statement:

WEATHER COMMENT: Mon Aug 30 22:39:13 GMT 2010 Clouds clouds everywhere. Insturments have been idled


To two places:

  1. Alice’s request
  2. The raw data files from MLSO used to produce the image in question. The weather comment was made at MLSO, so these data products are ones most relevant to the comment entry. Through provenance-based inference, the flags on these entries will carry over to any resultant data products (which could include one or more intensity pictures).

Scenario Aftermath:

For any future users (including Alice) looking at the provenance for 20100830.223717.chp.hsc.fts, a flag will be raised that the image quality has been impacted by weather, based on the information provided by Bob.
