initfile put

Replace the current initialization file with the body of the request.

arguments

  • restart, boolean (default: true)
    If true, then any running shared backends will be restarted. This ensures that subsequent requests will use the new initialization file.
  • warnings-are-errors, boolean
    If true then warnings are considered errors and will cancel the upload
  • verbose, boolean
    If true then the compiler will write compilation messages to the agraph.log file
initfile delete

Remove the server's initialization file.

jobs get

Returns lists of strings of the form ("uuid" "age" "description" [unused]), where "uuid" is the job UUID; "age" is the time since the job was created, in seconds; and "description" is the query string. Only query jobs are returned. The fourth element of the list will also be a string but is not currently used and so is not meaningful.

jobs delete

Cancels the specified job.

arguments

  • jobId, string
largeOperationWarning get

Return the text used for the large operation warnings.

largeOperationWarning put

Set the text used for the large operation warnings.

logfile get

$test-type  
$test-resolution  
$test-width  
$test-min  
$test-max 

The REST command returns a description of the nD-geospatial subtype specified by the parameters to the query. Currently, this can either be in text/plain or application/json.

arguments

  • datatype, string
  • all-vars, vars
processes get

Returns a list of tuples describing the server's currently running processes.

Each tuple has pid (the OS process ID), name (the process name), and displayName (a prettier name to use for display) properties.

processes / [NAME] get

Returns stack traces for the threads in the given process.

processes / [NAME] delete

Kills the specified process.

This should only be done if absolutely necessary as it can have adverse effects on the functioning of the server.

processes / [NAME] / telnet post

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.

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 context 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-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, string
    Used to set the named graph into which new triples are stored when the format does not itself supply one.
  • 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.
  • extermalReferenceTimeout, 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.

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.
