What if you could search across all of the notes you have in the books in your library or on a particular shelf?
What if for education titles you could search across your current textbooks? Or could collect the notes you have to easily study for a test?

> Hello,
> 
> The Portable Network Graphics (PNG)  specification was published in 2003, as both a W3C Recommendation and as an ISO Standard, with identical contents.
> 
> Since then, errata have accumulated and there has been no Working Group to maintain the specification.
>   https://github.com/w3c/PNG-spec/issues <https://github.com/w3c/PNG-spec/issues>
> Also in the interim, new requirements have arisen which could be added to the PNG specification without harming the excellent interoperability and backwards compatibility of existing images, image creation software and image consuming/display software.
> 
> A charter for a new WG to maintain and develop the PNG specification is under AC review
>   https://www.w3.org/Graphics/PNG/png-2021-ac.html <https://www.w3.org/Graphics/PNG/png-2021-ac.html>
> In particular, a new feature for support for HDR imagery to the PNG format <https://github.com/w3c/ColorWeb-CG/blob/master/hdr-in-png-requirements.md> is expected to be added. Also, the existing and widely implemented Animated PNG <https://wiki.mozilla.org/APNG_Specification> extensions, which were not part of the formal specification, are expected to be added.
>   https://github.com/w3c/ColorWeb-CG/blob/master/hdr-in-png-requirements.md <https://github.com/w3c/ColorWeb-CG/blob/master/hdr-in-png-requirements.md>
>   https://wiki.mozilla.org/APNG_Specification <https://wiki.mozilla.org/APNG_Specification>
> APNG is already widely implemented, it is just a case of re-aligning the specification with implementations.
> 
> Adding HDR and WCG imaging support will use the existing ITU H.273 metadata. This method is expected to be more interoperable, and also produce smaller files, than the previous method pioneered by the Timed Text WG.
> 
> There is also an existing eXif tag, for EXIF metadata, again widely supported but not part of the 2003 PNG specification.
> 
> Due to the age of the PNG spec, ICC v.2 is supported but ICC v.4 is not mentions. However it is widely supported in practice. Also, the description of the ICC profile is currently restricted to Latin-1 and needs to be extended to allow UTF-8. Again, the specification needs to align with implementations.
> 
> The plan is also to add Web Platform Test tests for all of the new features.
> 
> If you are interested in contributing to this work, or even just interested to see it move forward, please contact your AC Rep to let them know and to encourage their support in this review. Chairs, please forward to anyone in your groups who may be interested. The review period ends 23:59, Boston time on 2021-08-18. 
> 
> I am happy to answer any questions on the technical proposals, or the scope of the proposed Group.
