> In a Linked Data environment servers have to fetch data off the web. The speed at which
such data

(1 thread = 
> 0.5 to 1MB approximately). This is why Java NIO was developed and why servers such as

are more

> actors (500 bytes per actor) are growing more viisible.
> Unless I am mistaken the only way to parse some content is using methods that use an

> InputStream such as this:
>     val m = ModelFactory.createDefaultModel()
>      m.getReader(lang.jenaLang).read(m, in, base.toString)
> That read call blocks. Would it be possible to have an API which allows
> one to parse a document in chunks as they arrive from the input?
