[Format] .jp2 / .jpx [Properties/Technologies] JPEG2000, an ISO standard and an intended replacement for the JPG format. [Description] The uptake of JPEG2000 has been relatively slow since its release in December 2000 with browser support still lacking. The format offers higher performance and lossless compression ratios aimed at minimising file size and compression artefacts. The format also differs from standard JPG in that it uses XML (the JPX format) to store metadata within the file and can include within this IPTC, GML and Dublin Core metadata elements[4] [Recommendations] 
The format is now widely being investigated as a viable format for preservation due to its use of lossless compression and scalability. Various institutions and organisations such as the Wellcome Library (Buckley 2009), the University of Connecticut (Lowe & Bennett 2009) and the Digital Preservation Coalition (Buckley 2008) have produced reports in the last few years that suggest JPEG2000 will become increasingly popular as a preservation format.
