Returns a set of catalogs that are available on this server. For each catalog, id and uri properties are returned, giving respectively the name of the catalog and the URL under which it is found. Properties named readable and writable indicate, for each catalog, whether the current user has read or write access to at least one repository in it. When repoCount is true, also include the number of repositories for each catalog.

If dynamic catalogs are enabled for the server (see the DynamicCatalogs directive), this can be used to create a new catalog.

Returns whether or not the whether the current transaction has any changes that require a commit.

Create a neighbor-matrix, which is a pre-computed generator.

Return true if given repository is currently in read-only (no-commit) mode, false otherwise.

When this mode is active, all commits from any clients will return an error which effectively prevents writing to the store. This is used to enforce read-only stores.

Returns the deleted triple purge operation rate limit (read IOs per second). 0 means no limit.

Sets the deleted triple purge operation rate limit (read IOs per second). Note that this setting is not persistent. It will revert to 0 the next time the database instance is started.

Returns a string that is the contents of the shard-info file for the repo, or the string "nil" if there is no shard-info file.

List triple store shards as named pairs of shard's identifier and spec strings:

  { id: <id>, spec: <spec> } 

in either JSON or plaintext representation.

Compute the embedding for text and add the text and embedding to the vector store. properties is a property list where the keys are strings and the values are either literals or resources written in ntriple format. If a value isn't in ntriple syntax then it is considered to be a literal.

Returns a JSON array containing JSON objects representing attribute definitions. If NAME is supplied returns an array containing a single JSON object, if an attribute of the given name exists, otherwise returns an empty array.

Examples:

[{"minimum-number":0,"maximum-number":1152921504606846975,"name":"attr","allowed-values":[],"id":1,"ordered":false}]

[{"minimum-number":5,"maximum-number":10,"name":"attr1","allowed-values":[5, 7, 10],"id":1,"ordered":true}, {"minimum-number":0,"maximum-number":20,"name":"attr2","allowed-values":[],"id":2,"ordered":false}]

Establishes or updates a triple attribute definition.

Attributes must be defined before they can be used. Defining an attribute establishes the name of an attribute and any constraints that should be placed on its use.

Deletes an existing attribute definition.

If the named attribute definition was found and deleted, returns true.

If the named attribute definition was not found: If error is true (the default), throws an error. If error is false, returns false/nil.

Note that attribute definitions cannot be deleted if they are in use by the static attribute filter. An attempt to delete an attribute definition while it is in use will result in an error.

Returns the current static attribute filter for the triple store.

Sets the static attribute filter for the triple store.

When set, only triples which match the filter will be returned by any query against the store.

Deletes the current static attribute filter for the triple store (if any).

Adds and commits sample patient triples to the database.
Returns the number of triples added.

Adds and commits sample phone call triples to the database.
Returns the number of triples added.

Returns a list of XIDs for transactions that have been prepared but not yet committed or rolled back.

Optimize the indices in the repository at the given effort level.

Schedules a background operation to purge deleted triples from the specified indices.

Cancels purge deleted triple job for the specified indices.

Attempts to page in and lock the specified indices or the string table into memory. String or index data added after this call will not be locked.

The ability to lock is limited by the 'memlock' rlimit and available memory. Increasing the 'memlock' limit requires Systems Administrator intervention.

Removes the specified index or string table locks.

Returns a subset of the store's metadata. Currently it returns the attribute definitions and static filter definition. The value may be saved or passed later to set-metadata; it must not be modified.

Merge the metadata in the metadata argument into the current metadata for the database. It is not currently permitted to change an attribute definition and doing so will result in an error. The metadata value must have come from an earlier call to get-metadata. After calling this function a commit-triple-store must be done to make the changes persistent.

compute the semantically closest top N (top-n) strings from a vector triple store

Return true if given repository is currently in read-only (no-commit) mode, false otherwise.

When this mode is active, all commits from any clients will return an error which effectively prevents writing to the store. This is used to enforce read-only stores.

Enable read-only (no-commit) mode. Requires superuser privileges.

Disable read-only (no-commit) mode. Requires superuser privileges.

return the value of a given property for the object object-id in the vector store

return the text for the object object-id from a vector store

Returns the report with specified path as a JSON object

Discards any local repository changes, then synchronize to the latest committed repository version on the server. Starts a new transaction.

Returns the deleted triple purge operation rate limit (read IOs per second). 0 means no limit.

Sets the deleted triple purge operation rate limit (read IOs per second). Note that this setting is not persistent. It will revert to 0 the next time the database instance is started.

Returns a string that is the contents of the shard-info file for the repo, or the string "nil" if there is no shard-info file.

Split a shard into two shards

Returns a cursor of all duplicate triples visible in db inside the current transaction.

• :db - defaults to the value of *db*

• :mode - specifies how triple equality is determined. It can be :spog or :spo and defaults to :spog.

• :return-extended-triples - if true, each cursor result will be an extended-triple

In case db is a distributed repository, this will look for and return duplicate triples across shards. The knowledge base repositores are ignored.

Deletes duplicate triples in repository.

The MODE argument determines the test used to determine equality when testing for duplicates. Options are quad-based equality (spog, the default) or triple-based equality (spo).

Returns a report on db's storage usage, detailing its total disk size, number of triples and active indices, as well as more detailed information about its flavors, memory chunks and obsolete chunks.

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.

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.

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

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

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

return true if store in a vector store

Preloads portions of the repository into RAM for faster access.

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

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.

Creates a new SNA generator under the given name.

Return the Solr settings for the repository.

Set the Solr settings for the repository

Execute a SPARQL or Prolog select query.

Arguments of the form $varname=value specify variable bindings. Variables appearing in the query can be bound to a specific value outside the actual query using this mechanism. The value must be an N-Triples encoded RDF value. For example, if the value is an IRI, it must be wrapped in angle brackets.

Return information about any defined SPIN functions

Return information about the SPIN function associated with uri.

Associate a SPIN function with uri.

Remove the SPIN function associated with uri.

Return a list of SPIN magic properties defined for the store.

Return information about the SPIN magic property associated with uri.

Associate a SPIN magic property with uri.

Remove the SPIN magic property associated with uri.

Split a shard into two shards

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.

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.

Delete statements (triples) by matching against their components.

All parameters are optional -- when none are given, every statement in the store is deleted. The patterns to match come in pairs for subject, predicate, object, and graph. When given, they should be specified in N-triples notation.The subjEnd, predEnd, objEnd and contextEnd can only by specified if their matching entries is also supplied. At most one end parameter may be supplied.
