Schritt 1: Finden des Normdatensatz der Proceedings-Reihe z.B. PPN 669696374 für CEUR-WS.
Die Verknüpften Publikationen sind im OPAC unter related publications aufrufbar.
Schritt 2: SRU-Abfrage der verknüpften Publikationen
Wie in der K10plus-SRU-Dokumentation beschrieben setzt sich die entsprechende CQL-Query aus drei Teilen zusammen:

First you need to install Solr (which requires a Java JDK): Download a tar or zipfile at http://www.apache.org/dyn/closer.cgi/lucene/solr/ and unpack it to a directory of your choice. Go into this directory and start solr running in jetty by: | |

- JSONPath is was created 2007, inspired by XPath. A formal standard is being created at https://github.com/ietf-wg-jsonpath/draft-ietf-jsonpath-base
- SQL/JSON path was created inspired by JSONPath and other query languages.
- jq is a programming language with strong support of JSON transformation
- JSON Pointer only references a single element
Most important conflicting difference between JSONPath and SQL/JSON path is $.["name"]
vs $."name"
and $[? filter ]
vs $?(filter)
.
Other JSON query languages

This is a quick draft of a data format specification to encode annotated character data to support overlapping markup, also known as standoff markup.
Everything is subject to discussion
- By now this is kind of a fork of atjson
- Ted Nelson's xanadoc EDL format
- OCR formats ALTO, PAGE, hOCR
- Mac OSX Core Text

Minecraft Pi Edition (mcpi) ist eine kostenlose Version von Minecraft, die speziell für den Raspberry Pi herausgegeben wurde. Sie basiert auf der Bedrock Version 0.6.0 aus dem Januar 2013, ist also schon etwas älter. Das Spiel bietet standardmäßig nur den Kreativmodus mit einer eingeschränkten Karte, kann allerdings programmiert werden.
Es gibt einige Anleitungen und Beispiele, die meisten davon allerdings schon etwas älter.
