Hi ALTOers,

I checked the JSON examples in draft-ietf-alto-cost-calendar-10. And I saw
the following syntax errors still left in the latest document:

In the IRD example in Sec 3.3,
- "meta/cost-types/num-throughputrating/cost-metric"
and "meta/cost-types/string-servicestatus/cost-metric" have trailing commas.
- missing a comma between
"resources/filtered-cost-map-calendar/calendar-attributes" and

In the FCM response example in Sec 4.1.3,
- missing a pair of { } inside the list value of

In the ECS response example in Sec 4.2.3,
- "meta/calendar-response-attributes" has a trailing comma.

In the Multi-Cost ECS response example in Sec 4.2.4,
- missing a comma between
"meta/calendar-response-attributes/cost-type-names" and
- "meta/calendar-response-attributes" has a trailing comma.

After fixed the syntax issues above, I used cURL to check the
Content-Length for all JSON examples. But I cannot get the same value as
the document gives.

Following is my result. But the Content-Length value for the response JSON
should be wrong. Because I just left the symbols "v1, v2, ..." but not the
concrete values in the JSON.

> Content-Length: 290
> Content-Length: 557
> Content-Length: 208
> Content-Length: 689
> Content-Length: 2542
> Content-Length: 373
> Content-Length: 967

My script and JSON files for the Content-Length checking can be found in my

Sabine, you told me you replaced the symbols "v1, v2, ..." by specific
values to evaluate the content-length. Not sure which values you
were using. But you can modify the JSON files and rerun my script to
evaluate the Content-Length.
