 A list of planned features for `graphy`, lossely grouped and sorted by priority.
 
-## Level 0: Speculative
- - `TurtleLoader` -- Directly loads triples into memory from serialized Turtle (unmarshalling).
- - `NTriplesExtractor` -- WASM-powered parser with lazy property getters for optimized reading when filters are present.
- - `SparqlResultsJsonReader` -- Single threaded streaming reader for application/sparql-results+json.
- - `N3Reader` -- Single threaded streaming reader for Notation3.
- - `RdfXmlReader` -- Single threaded streaming reader for RDF/XML.
- - `OwlManchesterReader` and `OwlFunctionalReader` -- Single threaded streaming reader for OWL Manchester Syntax and OWL Functional Syntax.
- - `BigInt` support.
- - Concise Term directive for serializing long literals.
+## Level 3: In Progress
+ - ES Module Support for top-level groups.
+ - `DenseDatacache` -- Datacache (w/o union, diff, etc) for storing many quads.
+
+## Level 2: Wanted
+ - `JsonLdReader` -- Single threaded streaming reader for JSON-LD.
+ - `NdJsonReader` and `NdJsonScriber` -- Explicit reader and scriber for 'Newline-Delimited' JSON.
+ - Line number, column, and byte positions of read error origin.
+ - `DenseDataset` -- Dataset (w/ union, diff, etc) for storing many quads.
+ - `FastDatacache` -- Datacache (w/o union, diff, etc) for storing and retrieving quads quickly.
 
 ## Level 1: Interested
  - `TurtleScanner` and `TriGScanner` -- Multi-threaded streaming readers for Turtle and TriG.
