This is tracked in LDflex/LDflex-Comunica#4, I'm not sure if there is any work to do in this repo for this feature.

@jairo-campos-JD @james-martin-jd Not entirely what you had in mind, but solid.data.clearCache() now clears the local cache as of v2.4.0.

Since LDflex is currently not using any websockets, it did not make much sense to use it just for cache invalidation. Rather, I assume that your application is already using websocjets, so whenever you see an update pass by, calling solid.data.clearCache(document) (the parameter being optional), you can get the desired result.
