> Dear CLREQ people,

> On behalf of the Japan DAISY Consortium, which I 
> chair, I submitted three issues to the W3C GItHub 
> for accessibility.  They are proposals to introduce  
> three sets of Schema.org metadata for accessible 
> Japanese EPUB publications.  Eventually, we hope 
> to introduce equivalent metadata to ONIX.

> Dear colleagues,
> 
> I am writing this mail on behalf of the Technical
> Committee of the Japan Daisy Consortium.
> 
> I would like to share with you specifications that
> have been developed in the Technical Committee.
> These are intended to compliment ISO/IEC 23761 EPUB
> accessibility and LIA guidelines by providing
> functionalities specific to the Japanese language.
> 
> Eventually, we hope that metadata for these features
> be registered at both Schema.org and ONIX, and that
> they will be mentioned in the upcoming JIS version
> of ISO/IEC 23761.  These specifications are
> preparations for such metadata.
> 
> In a nutshell, we would like to allow Japanese users
> with print disabilities to find accessible EPUB
> publications.  For example, users will be able to
> find general-ruby EPUB publications from a large
> collection of EPUB publications easily.  See JLreq
> for the definition of general-ruby.
> 
> There are three groups of specifications.  The first
> group is concerned about ruby.  The second is
> concerned about the use or non-use of space as word
> dividers (wakati-gaki).  The third group is
> concerned about switching of horizontal writing and
> vertical writing.

> All specifications are available at:

> The current editors' draft of CSS Text Level 4 <https://drafts.csswg.org/css-text-4/> has properties
> for using space as word dividers (wakati-gaki).  We

> I explained these specifications in a recent meeting
> of the Chinese Text Layout task force (clreq)  <https://w3c.github.io/clreq/homepage/>within
> the W3C Internationalization Interest Group.
> 
> We have also been in close contact with Florian and
> Fantasai in the CSS WG.  In particular, we are aware
> of ongoing development of CSS Ruby <http://drafts.csswg.org/css-ruby-1/>.
> 
> Our next step is to raise GitHub issues for
> requesting ONIX metadata and Schema.org metadata
> based on our three groups of specifications.  Meanwhile, 
> the taskforce for Alternate Style Tags should prepare 
> a new draft (based on the W3C member body submission 
> for Alternate Style Tags).
