NASA provides two XDF APIs, in Perl and in Java. XDF is used to store high-dimensional data and information related to it in compact XML format. The purpose is to have interchangeable and high quality format that can be used as a main archive format for this kind of data. [1] The XDF project and related development have been halted (2002,2006).
The XDF reveals galaxies from 13.2 billion years ago, including one thought to have formed only 450 million years after the Big Bang. [6] On June 3, 2014, NASA released the Hubble Ultra Deep Field 2014 image, the first HUDF image to use the full range of ultraviolet to near-infrared light. [7]
On 11 October 2022, the James Webb Space Telescope spent over 20 hours observing the long-studied Ultra Deep Field of the NASA/ESA Hubble Space Telescope for the first time. [ 18 ] The HDF galaxies contained a considerably larger proportion of disturbed and irregular galaxies than the local universe; [ 10 ] galaxy collisions and mergers were ...

[45] [46] Previously in 2012, there were about 50 possible objects z = 8 or farther, and another 100 candidates at z = 7, based on photometric redshift estimates released by the Hubble eXtreme Deep Field (XDF) project from observations made between mid-2002 and December 2012. [47]

I took a look at the NASA press releases and accompanying photos. Apparently, NASA is responsible for the confusion. When they released their 2014 version, they called it 'HUDF' even though it was same field of view as the 2012 XDF and not the field of view of the 2004 HUDF. It appears to be actually an enhancement of the 2012 'XDF' but I'm not ...
