Core Link Format

RFC6690 Constrained RESTful Environments (CoRE) Link Format

Ausgabe einer '/.well-known/core' Abfrage eines Sensorknotens:

coap://[aaaa::0221:2eff:ff00:1f15]:5683/.well-known/core

</.well-known/core>;ct=40,
</s/button>;title="Button";rt="button",
</a/led1>;title="Led1";rt="led",
</s/temp>;title="Temperatur DS1820";rt="temperature-c",
</s/hum>;title="Humidity DHT11";rt="humidity-%",
</info>;title="Info";rt="Text",
</s/cputemp>;title="Temperature status";rt="temperature-c"

Resourcen eines Knotens sollten in Gruppen eingeteilt werden.

Sensoren:
/s/xxx

Aktoren:
/a/xxx

Dieses Attribut sollte den Namen der Resource in einer für Menschen verständlichen Form wiedergeben.

Beispiele:

title="Button"
title="Led1"
title="Temperatur DS1820"
title="Humidity DHT11"
title="Humidity SHT11"

Dieses Attribut sollte die Anwendunsspezifische Bedeutung der Resourece wiedergeben

Beispiele:

rt="button"
rt="led"
rt="temperature-c"
rt="humidity-%"
rt="text"
