Ok, why is this done like this?
Since this can be done in 1 conversion from the top…
I know this is an implementation only (e.g. I am not aware that this is on the 
wire this way..), but now we need to maintain code that does this..

Kind Regards,

Subject: Re: [dev] .dat files not being .gitignored?

The .dat files are cbor but the cbor2json tool does some things that are 
unusual that makes them a little less convenient.

For example:

If you pass

    "acl": {
        "aclist2": [
                "aceid": 1,
                "subject": { "conntype": "anon-clear" },
                "resources": [
                    { "href": "/oic/res" },
                    { "href": "/oic/d" },
                    { "href": "/oic/p" },
                    { "href": "/oic/sec/doxm" }
                "permission": 2
        "rowneruuid" : "31313131-3131-3131-3131-313131313131"

Json2cbor tool will encode everything after “acl”: into cbor then insert that 
into the final cbor output as a byte array as the value contained in acl

If you pass this value to a cbor2json decoder you will not get the json shown 
above you will get:

    "acl": <an array of bytes depending on the decoder this could be in a 
format like base64>

You must then take the array of bytes to the right of acl and decode them using 
a cbor2json decoder to find out the actual value.

See https://jira.iotivity.org/browse/IOT-2849 for a more in depth description. 
Using the “doxm” tag instead of the “acl” tag.

The unusual way json2cbor has actually made learning and understanding 
iotivity’s security much harder for me since it has made inspecting the *.dat 
files more difficult.

Really, we should get to a point where they don't need to be checked-in

that can't be the case right now because of cross-building.

I gather from all this that the .dat files are not cbor? I was under the 
impression that cbor is platform-independent. No?
