MetaProxy was originally developed to demonstrate the difference between indexing and physical organisation of resources. It uses a low-tech solution called "buddy files" to viewing and maintaining meta-data (e.g. captions, annotations, archival descriptions) for images and other file types. Because it does not involve any changes to the images then it is an ideal way of annotating digital photographs and images of historical documents, and so it is used by SVG Family-Tree Generator for its image albums.
Other advantages of this solution include:
Latest version is 3.0.0
"MetaProxy (v3.0)" (22 May 2020).
"Tool for Annotating Image Files" (8 Feb 2019).
