1. Calculating and Recording Coordinate Metadata on OPO Newscenter Press Release Astronomical Images: Project Overview, Status Report and Recommendations for Migration Lisa Frattare on behalf of Tony Rogers and Jessica Kenney Presented 12/4/2014 {hst_pr_sia_opo_all_hands_2006_12_06.ppt}

CHAI: Coordinates for Hubble Astronomical Images CAPRI: Coordinates for Astronomical Press Release Images AVM : Astronomy Visualization Metadata VAMP: Virtual Astronomy Multimedia Project NVO/VO: National Virtual Observatory SIAP: Simple Image Access Protocol CHAI: Coordinates for Hubble Astronomical Images CAPRI: Coordinates for Astronomical Press Release Images AVM : Astronomy Visualization Metadata VAMP: Virtual Astronomy Multimedia Project NVO/VO: National Virtual Observatory SIAP: Simple Image Access Protocol ACRONYMS ACRONYMS

3. Press release images are made from FITS telescope data

4. Image Pixels Image Header

5. Coordinate Information is lost in Press Release Images due to rotation, cropping, resizing

6. Software to Measure WCS: Pinpoint* Target Image: Press release TIFF Reference Image: FITS data (WCS) * wcs.py << IRAF kiss.kastrom 1995 LMF

7. Resultant Image: TIFF image with coordinate info embedded in header

8. Artwork Composite Print layout Moving Targets Non-coordinate Image Types “Must be astronomical from edge-to-edge.”

9. Astronomical only - these are considered “able” Astronomical w/ notation “compass” files Further Limiting of the Sample

10. Virtual Observatories -> VAMP (JPL/Spitzer) -> AVM Digital data, digital connections, digital processing Many telescopes, many repositories, many bandpasses Define standards Build infrastructure & tools Not best suited for Hubble Data Not best suited for Hubble Data

11. Many of these collections are now obsolete Need to (re)think permanence, archival, long-term investment and maintenance on collection to make it available for decades CHAI / MAST-like Projects in the Past

15. NASA Metadata Standard Dublin Core Metadata Initiative (DCMI) dc:tagname dcterms:tagname Minor Impact: NASA naming convention: STSCI- 2014-24-e.tif

17. Hubblesite Migration Objective: To efficiently tag and deliver press release images on-the-fly Main Task: Create an EASY mechanism/tool to update Hubblesite image with repeated changes to title/credit/caption/factsand push live (admin of Hubblesite) Secondary Task: To increase ability for anyone to tag or make changes to current tags with minimal effort. Current scheme is expert-friendly only. Impact to News Production: Minor at first with pre-tagged images Delivery of pre-tagged images by Lisa & Zolt that could include: Boilerplate: creator/publisher Pinpoint: spatial Distance, proposal/data info Spectral info, categories, subject name Proxy title, headline, caption

18. Current Procedure: Facts + Image Products = Hubblesite Release Image products delivered ~1 week before. Edits to text occur within days/hours of release. Proposed Workflow Change: Marry metadata to single image and make daughter products Update header information repeatedly as necessary Second-Phase Modifications for News: (more hands-on) Transfer Metadata from TIFS to non-astronomical images or other presentations of the same object: detail crops, full sized images, black and white, composite (UVIS/IR) i.e. caption of image “a” applied to all other images in that release

19. Other Migration Discussion Points: Writer to detach press release info from image: i.e. press release caption to generic description Discuss Hubblesite/NASA required metadata and where that can be auto-inserted i.e. constellation, 1 st paragraph summar Other images to tag: Moving Target, non-Hubble Initial discussion with: (at the very least) Carlos (programmer) Lacey (management/on-line outreach) Kelly (ingest for Hubblesite) Lisa (prepares release facts) Tony (MAST programmer) Jessica (AVM/MAST STPR) (later with anyone else impacted by the changes: Cheryl, Zolt, writers, etc.)
