+
+Querying Events by Tags Structure
+---------------------------------
+
+`draft` `optional` `author:fernandolguevara` `requires:nip-12`
+
+This NIP allows clients to query events from relays where a specific tag is present in the event's structure.
+
+The filter condition matches if there is at least one tag name in common with the filter and event.
+
+Example Subscription Filter
+---------------------------
+
+Below is an example filter that matches events with a `g` tag in their structure:
+
+```json
+{
+  "tags": ["g"]
+}
+```
+
+Suggested Use Cases
+-------------------
+One of the suggested use cases for this NIP is for location-specific events. Clients can utilize the provided filter example to locate events with specific location-related tags, regardless of how the location information has been stored in the events.
