There are some inconsistencies in the open data model descriptions:

• There are long and bigint types for timestamps.
• Ipv4 addresses are declared as long but int is enough.
• Ipv6 addresses are declared as bigint.
• http info status are explicitly declared as http_info_status when it is just a specific case of http_code_status.

Here is a modified version of the open data model trying to fix the previous inconsitencies. Following avro types I have used:

• int for 32bit
• long for 64bit.
  Avro does not have a type for 128bit. I have use int128 as type definition for the ODM. Avro definition should look like:
  {"type": "fixed", "name": "128bit", "size": 16}
