Description

Currently we save every URI ever qname'd forever in here: https://github.com/RDFLib/rdflib/blob/master/rdflib/namespace.py#L289

If you serialize a big graph in a store that is off disk, we may run out of memory.

Either:

• Add a lru_cache (from py3 functools + this 2.7 implementation
• Depend on

Server giving commit id in the returned JSON when there are updates

Debug logging for lifecycle methods like initialization and when data has to be re-inferred (eg. when something is deleted).

Trace logging would be per statement to log what gets inferred.

Currently, HeaderUtil.ts methods such as parseAccept, parseAcceptCharset, parseAcceptEncoding return an array of AcceptHeader values rather than a ValuePreferences object. The conversion currently happens in AcceptPreferenceParser, but it seems better to generate it correctly from the source.

Might be taken together with #469.

Hi, Is it possible to add in readme more information about support?

• What are the feature necessary for LDflex to work?
• Is Node supported?
• Are browsers supported? Which ones?
• Can polyfills help?
