# Linda

**[Linda](https://en.wikipedia.org/wiki/Linda_(coordination_language))** is a coordination model using a shared **tuple space** where processes write and read tuples matching patterns, decoupling producers from consumers in both space and time. Unlike [[sync-csp|CSP]], there is no direct addressing; all interaction goes through the shared associative memory.

Linda provides generative communication: produced data persists until consumed.

## Example

This example shows tuple-space operations and pattern matching:

```
out("task", 42)           // write tuple to shared space
in("task", ?x)            // remove matching tuple, bind x=42, block if none
rd("task", ?x)            // read tuple without removing it
```
