Coordinate Metadata














Instructions for each field: Publisher of the resource. ID of publisher registered as VAMP providers. This identifies a specific "instance" of a resource; e.g. one image in one file format at one resolution. This allows the same resource (image) to be offered in different formats and resolutions. Together with the PublisherID, each registered resource is uniquely identified in the database. A unique URL pointing to the specific online image/image archive is needed to identify where to obtain the image. Each ResourceID is paired with a matching ResourceURL. The format is a list of PublisherID/ID values that will reference specific resources registered in VAMP (though not specific "instances"). The date of the metadata content for the image. This is the version of the applied metadata definition (YYYY-MM-DD).

How to use the AVM Web Tool:
  • The AVM Web Tool has an entry for 52 AVM tags. Once completed and submitted it will generate an XML file in the Adobe XMP format. This file can then be attached to an image header using tools in Adobe Photoshop or Adobe Bridge.
  • Use only the fields that are necessary to properly tag your astronomical image. The tool does not require you to complete every field. Keep in mind that there is no validation of form inputs, so some fields may not be understood by Adobe's software unless it has been properly entered.
  • Instructions for each field appear at the top when the field is active. Use these hints if unsure about a particular field, or need guidance for the correct input format.
  • The Subject.Category field under the Content Metadata section links to a widget. The widget is used to retrieve numeric codes for taxonomy purposes — the taxonomy list is part of the AVM standard and VAMP project.
  • Note that on the Observation Metadata panel you can add additional form fields. You should use as many form fields as there are datasets contributing to a composite image. For instance, a 3-color RGB image composited from three different observations should have three sets of fields, one describing each observation.
  • You should use a dash "—" character as a placeholder in tags that can take multiple values when specific instances are missing. These include Distance (when you include a redshift value but not a distance in light years) or any of the Observation fields. Note that if none of the values are known for a tag they should all be left blank. Placeholders are needed only when some fields are known for a tag but others are to be left blank.
