catalogs / [CATNAME] / repositories / [REPONAME] / size get

Returns the number of statements in the repository, as an integer.

arguments

  • context, list
    if supplied, the count is only for the specified named graphs
catalogs / [CATNAME] / repositories / [REPONAME] / sna / paths get

Execute an SNA path search from start to end.

The searchMode controls whether breadthFirst, depthFirst, or bidirectional search is used (breadthFirst is the default). The SNA generator can either be specified by name using the generator parameter (assuming, of course, that the named generator has been previously defined on the server). Alternately, a generator can be built dynamically from the predicate, predicateTo and predicateFrom parameters. Each of these can be specified multiple times. Each URI in the predicate list will be used to find undirected paths whereas each URI in the predicateTo and predicateFrom lists will be used to find objects and subjects (respectively).

The graph parameter, which can be specified multiple times, can be used to restrict path searching to triples in only the specified graphs.

If timeout is supplied, it must be a floating point number and it will be used to limit the duration of the path searching.

If limit is supplied, it must be a positive integer and at most this many paths will be returned.

Lastly, the maximumDepth parameter can be used to limit the total search depth.

The return value depends on the version parameter. If the version is 1, then it will be JSON list of lists where each sublist contains the nodes along a path including the starting and ending nodes. If version is 2, then the result will be a JSON object with two keys: "paths" and "status". "paths" will be a list of the paths found (as in version 1). Each node will be either a subject or object of the triples that created the path. "status" indicates the reason the search stopped and can be one of "complete", "limit-reached", or "timeout". If version is not supplied or is anything other than 2, then the version 1 format will be used in order to be backwards compatible. Version 1 support is deprecated and will be phased out in the future.

arguments

  • end, string
  • maximumDepth, integer
  • searchMode, string (default: breadthFirst)
  • predicateTo, list

catalogs / [CATNAME] / repositories / [REPONAME] / statement put

Add a triple to the repository.

The subj, pred, and obj arguments must be supplied and are used to fill in the subject, predicate and object parts of the triple. The context argument is used to fill in the triple's graph but may be left off. In this case, the triple's graph will be the default graph of the repository.

The subj, pred, obj, and context (if supplied) arguments must all be in URI encoded N-Triples notation.

The service returns the triple-ID of the newly added triple.

arguments

  • subj, string
  • pred, string
  • obj, string
  • context, string
  • attributes, string
    If supplied, this must be a JSON object encoding of a list of key/value pairs. Keys must be strings and values must either be strings or arrays of strings. Each key must name an already existing attribute defintions.
catalogs / [CATNAME] / repositories / [REPONAME] / statements post put

Add triples to the triple-store.

This service can add triples in several ways:

  • Via a SPARQL Update command. To do this use the update parameter. The baseURI, context, remove-graph-uri, insert-graph-uri, using-graph-uri, using-named-graph-uri and infer parameters are all used in this case. Note that you can also send a POST request directly to the repository where the body of that request contains the update command.

  • Via AllegroGraph's bulk-load tool agload. In this case, the file or url parameters specify the location of the data to be loaded. The bulkLoad, bulkLoaders, externalReferences, baseURI and context parameters are used as parameters to agload.

  • Via AllegroGraph's direct load facility. The source of the data can be either from a file, located at a url or directly included in the body of the request. In the latter two cases, the request's Content-Type header or the query's type parameter must be used to specify the type of the data. You can use continueOnError, commit, context, baseURI and externalReferences parameters to control the load.

When the PUT method is used, triples in the supplied contexts are first deleted (if no context is supplied, then the store is completely emptied), whereas the POST method just adds triples. The value returned is an integer indicating the number of triples loaded.

The Content-Type header determines the way the given data is interpreted. The following formats are supported:

  • text/plain for N-triples
  • application/rdf+xml for RDF/XML
  • text/x-nquads for N-quads
  • application/x-extended-nquads for Extended N-Quads
  • application/trix for TriX
  • text/turtle for Turtle
  • application/json for JSON data (an array of arrays of strings, with the inner arrays having 3-5 elements each. The 5th element being a JSON string containing JSON attributes. Keys and values must be strings. The 4th element may be null.) Returns the number of triples added. Inner array format: [s, p, o] - for a triple [s, p, o, g] - for a quad [s, p, o, g-or-null, attributes] - for a triple/quad with attributes attached.
  • application/ld+json for JSON-LD data
  • application/x-rdftransaction for a transaction XML document
  • application/x-buffered-triples - internal format for flushing buffered triples for remote-triple-store.
  • application/x-franz-guess-format for guessing format based on contents of request.

Small data sources are best loaded via the direct facility whereas large data sources should be loaded via agload.

arguments

  • useAgload, boolean
    If true, then AllegroGraph's agload command-line tool will be used for the load.
  • attributes, string-or-nil
    If supplied, this must be a JSON object encoding of a list of key/value pairs. Keys must be strings and values must either be strings or arrays of strings. Each key must name an already existing attribute defintion.
  • baseURI, string
    When loading RDF/XML or JSON-LD data, the value of this parameter is used as the base URI of the document.
  • bulkLoaders, integer
    The number of loading processes to use when using the agload bulk load tool.
  • bulkLoad, boolean
    If true, then the triple-store will be put into bulk load (non-transactional) mode for the duration of the load.
  • commit, integer
    Will cause a commit to happen after every N added statements. Can be used to work around the fact that importing a huge amount of statements in a single transaction will require excessive amounts of memory.
  • context, list
    Used to set the named graph into which new triples are stored when the format does not itself supply one. This option can have multiple values, but only the first one will be used unless overrideContext is true.
  • overrideContext, boolean
    Force replacing graph information supplied in source data with the ones provided via context. If context is not provided, the graph from the data source will be used. For statements in the data source that do not contain graph information the default graph will be used.
  • continueOnError, boolean
    A boolean (which defaults to false) that indicates whether the load should continue when malformed data is encountered. Currently only works for N-Triples and N-Quads data.
  • uploadedFile, string
    Filename of file being uploaded for import. If set, the body of request will be interpreted as the contents of the uploaded file.
  • file, list
    A server-side filename from which to load the data. Note that eval permission is required to use this option. This option can have multiple values.
  • infer, string
    If true, then SPARQL Update commands will run with RDFS++ reasoning enabled.
  • insert-graph-uri, string
    Used for SPARQL Update requests to specify the graph into which to insert triples.
  • relaxSyntax, boolean
    If true, then less validation is done for the N-Triples and N-Quads formats. See the agload documentation for more details.
  • remove-graph-uri, list
    Used for SPARQL Update requests to specify the graph from which triples will be removed.
  • externalReferences, boolean
    A boolean (default is false) that indicates whether external references in RDF/XML and JSON-LD source files will be followed. When true, the caller must have eval permissions.
  • externalReferenceTimeout, integer
    Used to specify the timeout (in seconds) for loading contexts from 3rd-party web-sites.
  • type, string-or-nil
    May be used to specify the format of data in the body of the request or in the linked URL. Overrides the Content-Type header.
  • update, string
    A SPARQL Update command that will be evaluated to modify the triple-store.
  • url, string
    A url from which to load the data via an HTTP request.
  • using-graph-uri, list
    Used to specify the dataset for SPARQL Update commands.
  • using-named-graph-uri, list
    Used to specify the dataset for SPARQL Update commands.
  • jsonLdContext, string
    Used to provide an external context for JSON-LD loading.
  • jsonLdStoreSource, boolean
    Used to specify if the JSON-LD source should be stored.

  • attributeFilter, string
  • returnExtendedTriples, boolean
catalogs / [CATNAME] / repositories / [REPONAME] / statements / transform post put

Similar to /statements/ but is used for loading documents that don't represent RDF data directly and should therefore be pre-processed according to format-specific rules. The data to load is obtained from the request body.

In addition to specific rule parameters like TR-ID, TR-PREFIX, etc., the TRANSFORM-RULES parameter may be used to specify transformation rules.

If submitted as an HTTP POST request, then the new triples are added to the CONTEXT graph. If a PUT is used, then any existing triples in that graph are first removed.

Currently handles (TYPE or CONTENT-TYPE) JSON, JSONL, and CSV documents.

The special parameters for each content-type are prefixed accordingly. For example, CSV-COLUMNS, JSON-STORE-SOURCE, etc.

The HTTP response body contains the number of triples added.

arguments

  • attributes, string-or-nil
    If supplied, this must be a JSON object encoding of a list of key/value pairs. Keys must be strings and values must either be strings or arrays of strings. Each key must name an already existing attribute defintion.
  • commit, integer
    Will cause a commit to happen after every N added statements. Can be used to work around the fact that importing a huge amount of statements in a single transaction will require excessive amounts of memory.
  • context, string
    Used to set the named graph into which new triples are stored.
  • type, string-or-nil
    May be used to specify the format of data in the body of the request or in the linked URL. Overrides the Content-Type header.
  • transform-rules, string
    Used to reference the additional per-element transformation rules that should be already stored in the CONTEXT graph.
  • tr-id, string
    Tranformation rule for specifying custom id template.
  • tr-prefix, list
    Tranformation rules for specifying custom predicate prefixes.
  • tr-rename, list
    Tranformation rules for specifying custom predicate renamings.
  • tr-type, list
    Tranformation rules for specifying custom object types.
  • tr-lang, list
    Tranformation rules for specifying custom object langs.
  • tr-transform, list
    Tranformation rules for specifying custom object transforms.
  • tr-skip, list
    Tranformation rules for specifying which keys to skip.
  • tr-graph, list
    Tranformation rules for specifying override graphs for particular keys.
  • json-store-source, boolean (default: true)
    Used to specify if the JSON source objects should be stored.
  • csv-columns, string
    Used to specify CSV column names if the CSV data doesn't contain a header. The names should be a comma-separated list. If not provided it is assumed that the CSV header row is present.
  • csv-separator, string (default: ,)
    Used to specify CSV separator character.
  • csv-quote, string
    Used to specify CSV quote character.
  • csv-whitespace, string
    Used to specify CSV whitespace characters. Should be a comma-separated list of characters.
  • csv-double-quote-p, boolean
    Used to specify usage of double quote in CSV parsing. If true quotes can be escaped inside quoted values by doubling the quote character.
  • csv-escape, string
    Used to specify CSV escape character.
catalogs / [CATNAME] / repositories / [REPONAME] / storeID get

Returns the ID of the triple-store. The ID is generated randomly when the triple-store is created. It is an array of four octets.

catalogs / [CATNAME] / repositories / [REPONAME] / storeID put

Update the triple-store-id of DB to NEW-ID. For internal use only. NEW-ID must be an (unsigned-byte 8) array as would be returned by a call to TRIPLE-STORE-ID.

arguments

  • new-id, string
    A triple-store-id as returned by (triple-store-id)
catalogs / [CATNAME] / repositories / [REPONAME] / suppressDuplicates get

Returns the store's current duplicate suppression strategy.

Duplicate suppression controls if and how AllegroGraph checks triples that are about to be committed against triples that already exist in the triple-store.

It can be:

* `false` - no duplicate suppression is in effect,  
* `spog` - on commit, do not add triples that match some existing triple on  
subject, predicate, object and graph, or 
  • spo - on commit, do not add triples that match some existing triple on subject, predicate, and object.
catalogs / [CATNAME] / repositories / [REPONAME] / suppressDuplicates put

Sets the duplicate suppression strategy for the store.

arguments

  • type, string (default: spog)
    This can be one of:
    • false - turn off duplicate suppression,
    • spog - on commit, suppress the addition of triples with matching subject, predicate, object and graph, or
    • spo - on commit, suppress the addition of triples with matching subject, predicate, and object
catalogs / [CATNAME] / repositories / [REPONAME] / suppressDuplicates delete

Disable duplicate suppression for the store.

This is the equivalent of using PUT /repositories/(name)/suppressDuplicates with false as the type argument.

catalogs / [CATNAME] / repositories / [REPONAME] / tlog / locker get

Returns the process id of the process which is holding the transaction log lock. If the lock is unlocked, returns 0

catalogs / [CATNAME] / repositories / [REPONAME] / tripleCache get

Returns the size of the triple-cache (SPOGI cache).

Returns zero if the cache is disabled.

catalogs / [CATNAME] / repositories / [REPONAME] / tripleCache put

Sets the size of the triple-cache (SPOGI cache).

arguments

  • size, integer
    The size to use for the cache. If left unspecified, then the default cache size is used.
catalogs / [CATNAME] / repositories / [REPONAME] / tripleCache delete

Disable the triple-cache (SPOGI cache).

catalogs / [CATNAME] / repositories / [REPONAME] / unique / [COLUMN] get post

Return the unique values for the specified column.

column must be one of:

  • subject, subj or s to return unique subjects,
  • predicate, pred or p to return unique predicates,
  • object, obj or o to return unique objects, or
  • graph, g, context or c to return unique graphs (contexts).

Use the subj, pred, obj and context arguments to limit the triples that are examined.

This can be very expensive in time and space on a large triple-store.

arguments

  • subj, string
  • pred, string
  • obj, string
  • context, string
catalogs / [CATNAME] / repositories / [REPONAME] / useSecondaryIndices get

Return whether or not the store should use secondary indices (UPI-maps).

catalogs / [CATNAME] / repositories / [REPONAME] / useSecondaryIndices put

Change the secondary indices (UPI-maps) usage setting.

arguments

  • type, string (default: true)
catalogs / [CATNAME] / repositories / [REPONAME] / useSecondaryIndices delete

Turn off secondary indices (UPI-maps) usage.

catalogs / [CATNAME] / repositories / [REPONAME] / uuid get

Returns a string representing the UUID of the triple-store.

catalogs / [CATNAME] / repositories / [REPONAME] / validate / shacl get

Perform validation of the specified repository according to the SHACL rules.

arguments

  • dataGraph, list
    IRIs of the data graphs to be validated. "default" indicates the default graph. The default value is "default".
  • shapesGraph, list
    IRIs of the shapes graphs to validate against. "default" indicates the default graph. If not supplied and no resources in the data graphs have the http://www.w3.org/ns/shacl#shapeGraph property, data graphs themselves are used.
  • shape, list
    IRIs of the shape nodes to which to restrict validation. Must be members of the shapes graphs.
  • focusNode, list
    IRIs of the data nodes to which to restrict validation. Must be members of the data graphs.

catalogs / [CATNAME] / repositories / [REPONAME] / warmup put

Preloads portions of the repository into RAM for faster access.

arguments

  • includeStrings, boolean (default: true)
    If true, string table data will be warmed up.
