| Apache VXQuery |
| |
| Apache VXQuery\x99 will be a standards compliant XML Query processor implemented in Java. |
| The XQuery processor supports the {{{http://www.jsoniq.org/}JSONiq}} extension to XQuery. |
| The focus is on the evaluation of queries on large amounts of JSON and XML data. |
| Specifically the goal is to evaluate queries on large collections of relatively small JSON or XML documents. |
| To achieve this queries will be evaluated on a cluster of shared nothing machines. |
| |
| There are lots of large collections of relatively small documents like e.g. the {{{http://www.sec.gov/info/edgar/ednews/dissemin.htm}EDGAR dataset}} or the {{{http://wiki.openstreetmap.org/wiki/Download}OpenStreetMap dataset}}. |
| However there are no XQuery processors available today that are capable of processing these datasets in parallel and making the contained information accessible. |
