Geographic information - Filter encoding (ISO 19143:2010)

ISO 19143:2010 describes an XML and KVP encoding of a system neutral syntax for expressing projections, selection and sorting clauses collectively called a query expression.
These components are modular and intended to be used together or individually by other International Standards which reference ISO 19143:2010.
ISO 19143:2010 defines an abstract component, named AbstractQueryExpression, from which other specifications can subclass concrete query elements to implement query operations.
It also defines an additional abstract query component, named AbstractAdhocQueryExpresison, which is derived from AbstractQueryExpression and from which other specifications can subclass concrete query elements which follow the following query pattern:
An abstract query element from which service specifications can subclass a concrete query element that implements a query operation that allows a client to specify a list of resource types, an optional projection clause, an optional selection clause, and an optional sorting clause to query a subset of resources that satisfy the selection clause.
This pattern is referred to as an ad hoc query pattern since the server in not aware of the query until it is submitted for processing. This is in contrast to a stored query expression, which is stored and can be invoked by name or identifier.
ISO 19143:2010 also describes an XML and KVP encoding of a system-neutral representation of a select clause. The XML representation is easily validated, parsed and transformed into a server-specific language required to retrieve or modify object instances stored in some persistent object store.
ISO 19143:2010 defines the XML encoding for the following predicates.
- A standard set of logical predicates: and, or and not.
- A standard set of comparison predicates: equal to, not equal to, less than, less than or equal to, greater than, greater than or equal to, like, is null and between.
- A standard set of spatial predicates: equal, disjoint, touches, within, overlaps, crosses, intersects, contains, within a specified distance, beyond a specified distance and BBOX.
- A standard set of temporal predicates: after, before, begins, begun by, contains, during, ends, equals, meets, met by, overlaps and overlapped by.
- A predicate to test whether the identifier of an object matches the specified value.
ISO 19143:2010 defines the XML encoding of metadata that allows a service to declare which conformance classes, predicates, operators, operands and functions it supports. This metadata is referred to as Filter Capabilities.

Geoinformation - Filter Encoding (ISO 19143:2010)

Information géographique - Codage de filtres (ISO 19143:2010)

L'ISO 19143:2010 décrit un encodage en XML et KVP d'une syntaxe neutre de système destiné à exprimer des clauses de projection, de sélection et de tri collectivement appelées expression d'interrogation.
Ces composants sont modulaires et destinés à être utilisés ensemble ou individuellement par d'autres normes que celles qui référencent l'ISO 19143:2010.
L'ISO 19143:2010 définit un composant abstrait, nommé AbstractQueryExpression, à partir duquel d'autres spécifications peuvent sous-classer des éléments d'interrogation concrets pour mettre en ?uvre des opérations d'interrogation.
L'ISO 19143:2010 définit également un composant d'interrogation abstrait supplémentaire, nommé AbstractAdhocQueryExpression, qui est dérivé du composant AbstractQueryExpression et à partir duquel d'autres spécifications peuvent sous-classer des éléments d'interrogation concrets qui suivent le modèle d'interrogation suivant:
Un élément d'interrogation abstrait à partir duquel des spécifications de service peuvent sous-classer un élément d'interrogation concret mettant en oeuvre une opération d'interrogation permettant à un client de spécifier une liste de types de ressources, une clause de projection optionnelle, une clause de sélection optionnelle et une clause de tri optionnelle afin d'interroger un sous-ensemble de ressources qui satisfont à la clause de sélection.
Ce modèle est désigné comme étant un modèle d'interrogation ad hoc du fait que le serveur n'est pas informé de l'interrogation jusqu'à ce qu'elle lui soit soumise pour traitement. Cela s'oppose à une expression d'interrogation mémorisée, qui est mémorisée et peut être appelée par un nom ou un identifiant.
L'ISO 19143:2010 décrit également un encodage en XML et en KVP d'une représentation neutre de système d'une clause de sélection. La représentation XML est facilement validée, analysée et transformée en un langage spécifique au serveur requis pour récupérer ou modifier des instances d'objets mémorisées dans certains stockages d'objets permanents.
L'ISO 19143:2010 définit l'encodage en XML pour les prédicats suivants: un ensemble standard de prédicats logiques: and, or and not (et, ou et non); un ensemble standard de prédicats de comparaison: equal to, not equal to, less than, less than or equal to, greater than, greater than or equal to, like, is null and between (égal à, pas égal à, inférieur à, inférieur ou égal à, supérieur à, supérieur ou égal à, comme, est nul et entre); un ensemble standard de prédicats spatiaux: equal, disjoint, touches, within, overlaps, crosses, intersects, contains, within a specified distance, beyond a specified distance and BBOX (égal, disjoint, touche, dans, chevauche, croise, intersecte, contient, à une distance spécifiée, au-delà d'une distance spécifiée et boîte englobante); un ensemble standard de prédicats temporels: after, before, begins, begun by, contains, during, ends, equals, meets, met by, overlaps and overlapped by (après, avant, commence, commencé par, contient, pendant, se termine, égal à, satisfait, satisfait par, chevauche et chevauché par); et un prédicat pour vérifier si l'identifiant d'un objet correspond à la valeur spécifiée.
L'ISO 19143:2010 définit l'encodage en XML des métadonnées qui permettent à un service de déclarer les classes de conformité,  les prédicats, les opérateurs, les opérandes et les fonctions qu'il prend en charge. Ces métadonnées sont désignées par le terme Capacités de filtre.

Geografske informacije - Kodiranje s filtrom (ISO 19143:2010)

Ta mednarodni standard opisuje kodiranje XML in KVP sistemsko nevtralne sintakse za izražanje napovedi, izbire in razvrščanja stavkov s skupnim imenom poizvedba. Te komponente so modularne in namenjene skupni ali posamezni uporabi v drugih standardih, ki se sklicujejo na ta mednarodni standard. Ta mednarodni standard opredeljuje abstraktno komponento, imenovano AbstractQueryExpression (abstraktna poizvedba), iz katere lahko druge specifikacije konkretne poizvedbene elemente razdelijo v podrazrede za izvajanje poizvedb. Ta mednarodni standard prav tako opredeljuje dodatno poizvedbeno komponento, imenovano AbstractAdhocQueryExpresison (abstraktna ad hoc poizvedba), ki je izpeljana iz abstraktne poizvedbe ter iz katere lahko druge specifikacije konkretne poizvedbene elemente razdelijo v podrazrede, ki upoštevajo naslednji poizvedbeni vzorec: abstraktni poizvedbeni element, iz katerega lahko specifikacije storitev v podrazrede razdelijo konkretne poizvedbene elemente, ki izvajajo poizvedbo, ki stranki omogoča, da določi seznam vrst virov, izbirni napovedni stavek, izbirni stavek za izbor in izbirni stavek za razvrščanje v poizvedbi podsklopa virov, ki ustrezajo stavku izbire. Ta vzorec se navaja kot ad hoc poizvedbeni vzorec, ker strežnik ni seznanjen s poizvedbo, dokler ni predložena v obravnavo. To je v nasprotju s shranjeno poizvedbo, ki je shranjena in se jo lahko uveljavi z imenom ali oznako. Ta mednarodni standard prav tako opisuje kodiranje XML in KVP sistemsko nevtralne predstavitve izbranega stavka. Predstavitev XML se zlahka potrdi, razčleni in pretvori v strežniško specifičen jezik, ki je potreben za iskanje ali spreminjanje primerkov predmeta, shranjenih v nekem obstojnem pomnilniku predmetov.
