SensorML 🛰️

A minimalist, testable Rust crate for parsing and serializing SensorML documents in XML and JSON. Designed for integration with mapping layers, adapters, and future transformation pipelines.

✨ Features

• Parse SensorML from XML and JSON
• Serialize SensorML to XML and JSON
• Validate sensor references and ISO 8601 timestamps
• High test coverage and mutation resistance
• Depends only on serde, quick-xml, and chrono

📦 Installation

Add to your Cargo.toml:

sensorml = "0.1"

📚 Example

use sensorml::model::{SensorMLDocument, Sensor, Observation};
use sensorml::format::json;

let doc = SensorMLDocument {
    sensors: vec![Sensor {
        id: "sensor-1".into(),
        sensor_type: "temperature".into(),
        unit: "Celsius".into(),
        description: Some("Outdoor sensor".into()),
    }],
    observations: vec![Observation {
        sensor_id: "sensor-1".into(),
        timestamp: "2025-10-11T10:00:00Z".into(),
        value: "18.5".into(),
    }],
};

let json = json::serialize_to_json(&doc)?;
let parsed = json::parse_from_json(&json)?;
parsed.validate()?; // checks sensor references and timestamp format
