Data Exchange Model for WebLab platform provided by EADS Query package - Version 1.0 - 2008/05 A query is a resource which contains request data. This data describe a each specific specialisation of query, in a specific format. The query object is then abstract and several specialisations will be used to describe any type of queries. A proposal is to adopt common standards in order to provide consistent definitions over all the WebLab platform. XQuery and SPARQL format has been identified as a promising candidate respectively for structured and semantic search. As a resource, a query could be annotated to provide, for example, meta-informations on its creation date, its author, etc. Data Exchange Model for WebLab platform provided by EADS Query package - Version 1.0 - 2008/05 This kind of query is only an aggregation of query using a n-ary boolean operator to combine them. Composing queries using various composed queries will enable to deal with brackets. Please note that when dealing with the operators AND and OR, the number of queries should be at least two to be used; used with a simple query it will have no effects. NOT is a unary operator, so the list of queries should be reduced to one, but when using it in a more-that-one-query list, a AND NOT operator will be used in fact. Data Exchange Model for WebLab platform provided by EADS Query package - Version 1.0 - 2008/05 The list of query to be composed using the operator, in the order of the list if it has effects. AND, OR or NOT operator to be used to combine queries. This is a simple restriction of String to reduce the values to the three boolean operators AND/OR/NOT. Note that in a n-ary context, the unary operator NOT is considered as a AND NOT. Data Exchange Model for WebLab platform provided by EADS Query package - Version 1.0 - 2008/05 A Boolean operator that narrows a search by requiring all of the search queries to be matched in the results retrieved. A Boolean operator that broadens a search by requiring any of the search queries to be matched in the results retrieved. A Boolean operator that narrows a search by excluding results of the given queries in the results retrieved. This kind of query is dedicated for search of document structure and thus the chosen syntax is XQuery. Data Exchange Model for WebLab platform provided by EADS Query package - Version 1.0 - 2008/05 The string query in XQuery syntax. This query is dedicated for full text search and thus its syntax is similar to current search engines. Data Exchange Model for WebLab platform provided by EADS Query package - Version 1.0 - 2008/05 The string query in a free text syntax. A list of attributes. This query is dedicated for semantic search and thus its syntax is SPARQL. Data Exchange Model for WebLab platform provided by EADS Query package - Version 1.0 - 2008/05 The string query in SPARQL syntax. This query is dedicated for search by similarity and thus its content is a resource. Data Exchange Model for WebLab platform provided by EADS Query package - Version 1.0 - 2008/05 The resource to be used as template. A list of attributes. This specific query allows to request on a list of facets using a key/value map. Data Exchange Model for WebLab platform provided by EADS Query package - Version 1.0 - 2008/05 A list of attributes. A simple container for two strings a key and its value to carry out faceted search for instance. The key The value
