Caroline,

Thank you for your careful review again.  In London, we studied your
comments carefully, although some of your comments need further
work.

Now, we use "media type" and "the Media Type stream" except in titles, part
property name, and RFC titles.
The list of all occurrences of "media type" is shown at the end of this
mail.  "Growth Hint" and
"Media Type" as part property names are also capitalized.

Capitalization of headings is left to final editing work after the
technical content
is mature.

Participants of the London meeting do not want to mention
[Content_Types].xml in earlier clauses.  This is because this file is
very specific to the ZIP physical package model.  Media type
information does not always require a particular file.  Even if a
particular file is needed, the file name is not required to be
[Content_Types].xml.

But we added

This clause specifies an abstract model for a package. The requirements for
mapping

these concepts to a physical format, including specifically to ZIP files,
are given in §9.

and

This clause specifies the requirements for mapping the abstract package
model

concepts in §8 to a physical format, including specifically to ZIP files as
described in §9.3.


at the beginning of  Clauses 8 and 9, respectively.

Now, we use " using the syntax defined in RFC 7231 3.1.1.1"

We plan to drop Annex G.  It hampers our editing work.  No other parts
have such lists of requirements.

Yes, we have deleted  the section.

We deleted the definition of "Media Type stream".  It is rather a provision.

Again we do not want to mention this file name in Clauses 1 thru 8.

First, we tried to avoid normative definitions of what is already defined
in MIME RFCs.
As a result, this subclause has much less text then before.  I will send a
revised text
very soon.

RFC 2046 provides a conceptual definition of media types.  RFC 7231
provides one possible syntax for specifying
media types.  Thus, we think that  8.2.3 should not reference RFC 7231.  We
think that 9.2.3 is the right place.

Yes, this is intentional.   RFC 7231 shouldn't get mentioned until Clause 9.

Again, the schemas provide syntax.  Thus, it should not be referenced from
Clause 8.

We defer editing work of [Mx,x:].  I would like to delete all of them.

Yes.   Done.

RFC 7231 is referenced in 9.2.3.2.3 and 9.2.3.2.4.  We  intend to
reformulate requirements on
producers/consumers as requirements on data, thus dropping M1.13.

We adopted the following.

For all other physical package formats, the package should include an XML
stream called the Media Types stream. [S2.2] The Media Types stream shall
not be mapped to a part by the package implementer. [M2.1] This stream is
therefore not URI-addressable. However, it can be interleaved in the
physical package using the same mechanisms used for interleaving parts.

Again, we think that 9.3 is the right place for introducing the file name
[Content_Types].xml.

Standardization side

Regulatsion side

Earlier directives, July


New regulation 
Two parts: (1) identification and (2) trust serices 

Developing technical
Aplicaable to signatures and electronic seals
99% equally to fields and transactions
Legal requirement

XAdES  

Regulartion 910 214:  eIDAS
Not made mandatory.
Some recommended standard is the new XAdES.
The new XAdES is the one required.

2016: one year switch over period

Standardiation

Over a few years, consultation.
Adopted to align with the regulation.
Based on feedbacks, we have received.
Approved document , now editorial update,
New weeks
Public download area of ETSI
In two ways

One: draft EN -> all member countries of EU

Two: technical specification of ETSI, available in a few weeks

EN 319 162-1aa

1. すでに調べてある系列を、変換結果から分類する。

問題は、まだ足りない分類結果があることだが、それは気にしないことにする。

分類を保存するような削減のしかたを調べる。保存できる削減があるのなら、これで解空間を間引く。
これが出来れば、高速化できる。もし、dをすべて削除できれば15から10に減る。


grep -v dをすればdをすべて削除した結果がわかる。



11手をすべて探求することは出来ている。

11手までであまり使われていない手があれば、それは除いてみよう。
11手までで使われている手順をリストする。


11手までであまり使われていない二手順があれば、それは除いてみよう。

11手までであまり使われていない三手順があれば、それは除いてみよう。

XAdES

  Does eIDAS encourage the use of the upcoming XAdES only or both the
  existing and upcoming XAdES?

  Are baseline profiles most important?  

  How will the schema be reorganized?

  Further comments possible?
  
Extensions

  Should an applicaion program ignore foreign parts older than standard parts?

  Should an application program always preserve foreign parts? Or, 
  should it discard them when they modify standard parts significantly?

  Should Part 1 require that SML applications should modify 
  the content of extLst when columns or rows are added or deleted?
