Group: org.apache.marmotta - All Dependencies

Marmotta Sesame Tools: Triple Table · Provides a simple in-memory table using the Java Collections API to access triples. Additionally, the triple table offers in-memory indexes for typical query operations (e.g. listing by subject).

KiWi Triplestore: SPARQL · Provides enhanced SPARQL evaluation support by translating certain query patterns directly into SQL. SPARQL operation is then a mixed in-memory and native evaluation with better performance than pure in-memory.

Loader: Core Library · Apache Marmotta bulk loader core functionalities, which need to be complemented with backend libraries implementing the concrete loading functionality.

Apache Marmotta Platform: KiWi Backend · This module provides an Apache Marmotta backend based on the KiWi triple store. This is a reasonable setting for most setups, provides more features than other backends and is therefore also the default backend for Marmotta.

LDClient Provider: RDFa Resource Access · This package allows the Linked Data Client to access HTML pages with embedded RDFa annotations as Linked Data.

KiWi Triplestore: Triple Table · Provides a simple in-memory table using the Java Collections API to access triples. Additionally, the triple table offers in-memory indexes for typical query operations (e.g. listing by subject).

KiWi Triplestore: Transactions · Extended transaction support for KiWi triplestores. Needed by reasoner and versioning.

Apache Marmotta Platform: Linked Data Caching (Common) · Provides common infrastructure for transparent Linked Data Caching in Marmotta. When a resource is queried using e.g. LDPath or SPARQL and it represents an external resource (e.g. on DBPedia or GeoNames), the resource is transparently fetched on demand and cached locally. This module contains the backend-independent services.

LDPath Functions: JSON · LDPath Functions for JSON content.

LDClient Provider: YouTube Resources · This package enables the Linked Data Client to access the metadata of YouTube Videos as if they were published as Linked Data (RDF) by mapping the YouTube API to the Ontology for Media Resources.

LDClient Provider: Vimeo Resources · This package enables the Linked Data Client to access the metadata of Vimeo Videos as if they were published as Linked Data (RDF) by mapping the Vimeo API to the Ontology for Media Resources.

LDClient Provider: MediaWiki API Access · This package allows accessing wiki articles stored in a MediaWiki installation, particularly Wikipedia. It accesses the wiki through the MediaWiki API to retrieve raw article data.

LDCache: Sesame SAIL (KiWi) · Stacked Sail that allows transparent access to resources through the Linked Data Cache, retrieving them on demand when needed. Can be wrapped around other Sesame SAILs.

LDCache: Sesame SAIL (Generic) · Stacked Sail that allows transparent access to resources through the Linked Data Cache, retrieving them on demand when needed. Can be wrapped around other Sesame SAILs.

LDCache Backend: KiWi · Linked Data Caching Backend based on the JDBC database used by the KiWi triple store. Caches resources and caching information in the database and triples in the central triple store (using a dedicated context graph).

LDCache Backend: Infinispan · Linked Data Caching Backend based on the Infinispan Data Grid. Will represent cache entries and triples in a distributed data grid in memory with dynamic cluster balancing.

KiWi Triplestore: Versioning · Provides versioning functionality on top of the KiWi triplestore, i.e. allows keeping a log of all changes carried out on the triple store as well as reverting to previous states.

KiWi Triplestore: Reasoner · This module implements the sKWRL rule-based reasoner for the KiWi triplestore. It allows defining custom rule sets over RDF data. sKWRL is a purely monotonic reasoner without negation and implemented using forward chaining on the database.

KiWi Triplestore: Infinispan Cache Backend · Infinispan cache implementation for the KiWi triplestore. Useful for more complex cluster configurations with shared caches.

KiWi Triplestore: Hazelcast Cache Backend · Hazelcast cache implementation for the KiWi triplestore. Useful for more complex cluster configurations with shared caches.
