WIS2 topic hierarchy and filename
Core hierarchy
Level | Name | Description | Value(s) | Example | |
|---|---|---|---|---|---|
1 | scope | Scope | Scope of topic hierarchy (fixed to |
|
|
2 | resource-type | Resource type | Type of resource being identified |
|
|
3 | data-policy | Data Policy | WMO Unified Data Policy category, provides distinction in access control/permissions |
|
other

4 | data-type | Data Type | Top level data type |

Examples:
wis2.data.core.observations
wis2.discovery-metadata.recommended.nwp
wis2.data.other.observations
...
wis2.monitoring-report.gts
Data Type Hierarchies
Level 3 Data Type hierarchies vary significantly across data types (e.g. different for observations and NWP), and will be built gradually following the requirements of WMO domains.
Each WMO domain will also define filename conventions (basename, extension)
Observation Data Type
Level | Name | Description | Value(s) | Example | |
|---|---|---|---|---|---|
1 |
category
2
Data category
observations…
observations
country | Country | ISO 3166-2 code of country |

2 | station-type | Station type | Station/platform type |

3 | message-type | Message type | The type of message sent by the observation station |

wis2.data.core.observations.gr.landMobile.??
wis2.data.core.observations.it.seaFixed.??
wis2.monitoring-reports.wis2.observations.de.??
Alternative Proposal
This alternative proposal has the country code and center name higher up in the hierarchie. Could be extended with data policy
