GOST - Go implementation of OGC SensorThings API
Hi, I have this URL to extract Things of a specific project and expand it to Locations and Datastreams/Observations [https://api-samenmeten.rivm.nl/v1.0/Things?$filter=contains(properties/project,%20%27HEI%27)&$expand=Locations,Datastreams/Observations](url) It returns 72 Things with its Location and I see...
In the SamenMeten programm we use the sensorThings API to store and publish the sensor-data. I made some R-code to get data from the API (https://github.com/rivm-syso/samanapir ). I am not...
Filtering a Thing by a property results in BadRequest. eg. `http://scratchpad.sensorup.com/OGCSensorThings/v1.0/Things?$filter=properties/hello%20eq%20%27world%27` or `http://scratchpad.sensorup.com/OGCSensorThings/v1.0/Things?$filter=properties%2Fhello%20eq%20%27world%27` ``` { "errorId": "f4a4818f-f4e4-46c9-abe1-fbde97b893f9", "code": "BAD_REQUEST", "message": "Invalid query. Invalid property.", "stclass": "com.sensorup.iot.model.ErrorResponse", "baseURL": "http://scratchpad.sensorup.com/OGCSensorThings/v1.0" } ```...
Sorry, I don't know if you are reponsable, but maybe you can forward it. Calling: http://scratchpad.sensorup.com/OGCSensorThings/v1.0/Datastreams Results in: ``` { "errorId": "64f5ba3c-77d3-4f5d-8174-424c1535ade8", "code": "BAD_REQUEST", "message": "Invalid query.", "stclass": "com.sensorup.iot.model.ErrorResponse", "baseURL":...
sometimes we observe Mosquitto server crashing, error message: ``` mosquitto: loop.c:489: loop_handle_reads_writes: Assertion `pollfds[context->pollfd_index].fd == context->sock' failed ``` version | mosquitto version 1.4.15 -- | -- timestamp | Sat, 07...
Our Observation-table contain some 67000000 records. Mostly they will be retrieved by using a filter on phenomenonTime. It takes up to 30 seconds to get the desired records. Is this...
GET v1.0/Datastreams(id) response can be slow or even return a timeout on a larger database. This problem occurs on our test server with around 25m observations. The slow performance is...
Hello there, I would like to create `Thing` and associated `Location` entities via MQTT, but I don't know if it is supported by the STA specification. Seeing *"mqtt support for...
Hello, I'm trying to filter a thing's locations, expanding its historical locations (since `Things(42)/Locations` only returns the current location); the objective is to match locations present in a given area....
drawbacks current MQTT solution: - need non-standard GOST prefix when publishing data using MQTT - supports publish/subscribe only on Observations Need to have a new design fixing those drawbacks (so...
