Dear core parameter experts,

In draft-ietf-ace-coap-est we want to allocate content format numbers to 
4 already existing media formats.
LWM2M people are implementing the est-coaps specification and want to 
deploy it as quickly as possible.
Therefore, they need to know the allocated numbers to write into their 
code.
An early allocation before publication of the draft as RFC will be 
appreciated.

Below the IANA text from the draft, using TBD1 - TBD4 as allocated 
numbers.

Many thanks,

peter

Hi Peter,

I see you=E2=80=99re requesting Content-Format IDs for the following existi=
ng media
types:

- application/pkcs7-mime
- application/pkcs8
- application/csrattrs
- application/pkcs10

A Content-Format is the combination of a media type and a content coding.
Please specify the content coding(s) you want to use with each media type.
The possible set of content codings can be found at
https://www.iana.org/assignments/http-parameters/http-parameters.xhtml#cont=
ent-coding

Please format your request as a table that looks like Table 9 in
https://tools.ietf.org/html/rfc7252#section-12.3 (one row for each
combination of a media type and a content coding)

It seems =E2=80=9Capplication/pkcs7-mime=E2=80=9C actually does define a me=
dia type
parameter, =E2=80=9Csmime-type =E2=80=9D. RFC 5751 says:

   Because there are several types of application/pkcs7-mime objects, a
   sending agent SHOULD do as much as possible to help a receiving agent
   know about the contents of the object without forcing the receiving
   agent to decode the ASN.1 for the object.  The Content-Type header
   field of all application/pkcs7-mime objects SHOULD include the
   optional "smime-type" parameter, as described in the following
   sections.


So it seems the parameter is more or less required. Do you want to register
a Content-Format ID for each defined smime-type value? Then the list of
media types (that need to be paired with a content coding) looks like this:

- application/pkcs7-mime; smime-type=3D=E2=80=9Cenveloped-data=E2=80=9D
- application/pkcs7-mime; smime-type=3D=E2=80=9Csigned-data=E2=80=9D
- application/pkcs7-mime; smime-type=3D=E2=80=9Ccerts-only=E2=80=9D
- application/pkcs7-mime; smime-type=3D=E2=80=9Ccompressed-data=E2=80=9D
- application/pkcs8
- application/csrattrs
- application/pkcs10

Klaus

HI Klaus,

Thanks for the quick reaction, and thanks for pointing out some existing 
other smime types.
I did a search in RFC 7030, and came up with other necessary smime 
types.

Below the table as required for est-coap draft: (I will change the draft 
accordingly)

- application/pkcs7-mime; smime-type=“server-generated-key”; Encoding = 
"binary"; ID = TBD1; Reference = RFC5751, RFC7030
- application/pkcs7-mime; smime-type=“certs-only”; Encoding = "binary"; 
ID = TBD2; Reference = RFC5751
- application/pkcs7-mime; smime-type=“CMC-request”; Encoding = "binary"; 
ID = TBD3; Reference = RFC5751, RFC5273
- application/pkcs8; smime-type = ---; Encoding = "binary"; ID = TBD4; 
Reference = RFC5958
- application/csrattrs; smime-type = ---; Encoding = "binary"; ID = 
TBD5; Reference = RFC7030
- application/pkcs10; smime-type = ---; Encoding = "binary"; ID = TBD6; 
Reference = RFC5967

I expect the Encoding is orthogonal to the media type and smime type 
specification.

Many thanks,

peter

What about =E2=80=9CCMC-Response=E2=80=9D?

There=E2=80=99s a registry for =E2=80=9Csmime-type=E2=80=9D values at
https://www.iana.org/assignments/media-type-sub-parameters/media-type-sub-p=
arameters.xhtml#smime
Would it make sense to simply allocate a Content-Format ID to each of them?

The media type and the content coding are orthogonal. However, =E2=80=9Cbin=
ary=E2=80=9D is
not a valid content coding. (It=E2=80=99s really confusing that the column =
is
labeled =E2=80=9CEncoding=E2=80=9D; content coding is what is meant.) Possi=
ble content
codings are listed in
https://www.iana.org/assignments/http-parameters/http-parameters.xhtml#cont=
ent-coding
You probably want the =E2=80=9Cidentity=E2=80=9C content coding.

=E2=80=9Capplication/pkcs8=E2=80=9D and the other two media types don=E2=80=
=99t have the
=E2=80=9Csmime-type=E2=80=9D parameter defined, so just remove that bit.

Otherwise the table looks good to me.

Klaus

&gt; Hi Peter,<br>
&gt; <br>
&gt; I see you=E2=80=99re requesting Content-Format IDs for the following<b=

&gt; existing media types:<br>
&gt; <br>
&gt; - application/pkcs7-mime<br>
&gt; - application/pkcs8<br>
&gt; - application/csrattrs<br>
&gt; - application/pkcs10<br>
&gt; <br>
&gt; A Content-Format is the combination of a media type and a content<br>
&gt; coding. Please specify the content coding(s) you want to use with each=
<br>
&gt; media type. The possible set of content codings can be found at<br>
&gt; <a href=3D"https://www.iana.org/assignments/http-parameters/http-param=

w.iana.org/assignments/http-parameters/http-parameters.xhtml#content-coding=
</a><br>
&gt; <br>
&gt; Please format your request as a table that looks like Table 9 in<br>
&gt; <a href=3D"https://tools.ietf.org/html/rfc7252#section-12.3" rel=3D"no=

&gt; <br>
&gt; It seems =E2=80=9Capplication/pkcs7-mime=E2=80=9C actually does define=
 a media<br>
&gt; type parameter, =E2=80=9Csmime-type =E2=80=9D. RFC 5751 says:<br>
&gt; <br>

&gt;=C2=A0 =C2=A0 sections.<br>
&gt; <br>
&gt; So it seems the parameter is more or less required. Do you want to<br>

Hi Klaus,

the updated table. some reactions to your very useful remarks further 
below. many thanks,

greetings,

&gt; What about =E2=80=9CCMC-Response=E2=80=9D?<br>
<br>
thanks, I missed that one.<br>
<br>
&gt; <br>
&gt; There=E2=80=99s a registry for =E2=80=9Csmime-type=E2=80=9D values at<=

&gt; Would it make sense to simply allocate a Content-Format ID to each of<=
br>
&gt; them?<br>
I prefer to only specify those used in RFC7030<br>
&gt; <br>
&gt; The media type and the content coding are orthogonal. However,<br>
&gt; =E2=80=9Cbinary=E2=80=9D is not a valid content coding. (It=E2=80=99s =
really confusing<br>
&gt; that the column is labeled =E2=80=9CEncoding=E2=80=9D; content coding =
is what is<br>
&gt; meant.) Possible content codings are listed in<br>
&gt; <a href=3D"https://www.iana.org/assignments/http-parameters/http-param=

w.iana.org/assignments/http-parameters/http-parameters.xhtml#content-coding=

&gt; You probably want the =E2=80=9Cidentity=E2=80=9C content coding.<br>
<br>
You are right. looks most probable one.<br>
&gt; <br>
&gt; =E2=80=9Capplication/pkcs8=E2=80=9D and the other two media types don=
=E2=80=99t have the<br>
&gt; =E2=80=9Csmime-type=E2=80=9D parameter defined, so just remove that bi=
t.<br>
&gt; <br>
&gt; Otherwise the table looks good to me.<br>

&gt;&gt;&gt; <br>
&gt;&gt;&gt; I see you=E2=80=99re requesting Content-Format IDs for the fol=

&gt;&gt;&gt; existing media types:<br>
&gt;&gt;&gt; <br>
&gt;&gt;&gt; - application/pkcs7-mime<br>

&gt;&gt;&gt; - application/csrattrs<br>

&gt;&gt;&gt; <br>
&gt;&gt;&gt; A Content-Format is the combination of a media type and a cont=

ith<br>
&gt;&gt; each<br>
&gt;&gt;&gt; media type. The possible set of content codings can be found a=

&gt;&gt;&gt; <br>
&gt;&gt;&gt; Please format your request as a table that looks like Table 9 =

&gt;&gt;&gt; It seems =E2=80=9Capplication/pkcs7-mime=E2=80=9C actually doe=

&gt;&gt;&gt; <br>
&gt;&gt;&gt; Because there are several types of application/pkcs7-mime<br>

&gt;&gt;&gt; a<br>
&gt;&gt;&gt; sending agent SHOULD do as much as possible to help a receivin=
g<br>

&gt;&gt;&gt; know about the contents of the object without forcing the<br>

 following<br>
&gt;&gt;&gt; sections.<br>
&gt;&gt;&gt; <br>
&gt;&gt;&gt; So it seems the parameter is more or less required. Do you wan=

&gt;&gt; Then<br>
&gt;&gt;&gt; the list of media types (that need to be paired with a content=
