Front end

catalogs get

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.

catalogs / [CATNAME] put

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

Returns the protocol version of the Sesame interface. The protocol described in this document is 4.

catalogs / [CATNAME] / repositories get

Return a list of repositories available in the catalog.

arguments

  • all, boolean
    If true, then all of the repositories in all of the catalogs will be returned.
catalogs / [CATNAME] / repositories / [REPOSITORY] put

Creates a new, empty repository.

When a repository with the given name already exists, it is overwritten, unless a parameter override with value false is passed.

arguments

  • expectedSize, integer
    Specifies the expected number of triples in the repository

Returns a JSON object containing information about all pending and a limited number of finished requests for all AllegroServe instances running. This includes requests to the main AllegroGraph URL, the backends and sessions.

Each request contains the following information: - uri - the URL of the request - method - one of HTTP methods like 'get', 'post', etc. - statusCode - response status or null (if request not finished yet) - source - IP and port of the requester - started - Unix timestamp (in nanoseconds) of the moment the request was received by the server - finished - Unix timestamp (in nanoseconds) of the moment the server finished answering the request, or null if the request not finished yet. - duration - Duration of the request in nanoseconds. For pending requests, this is the duration of the request until now.

Requires superuser privileges.

roles / [NAME] put

Add a new role to the server.

roles / [NAME] delete

Remove the role named name from the server.

roles / [NAME] / access get

This returns a result set, each element of which has a read, write, catalog, and repository component. The first two are booleans, the latter two strings. For permissions granted globally, catalog and repository will have a value of "*", for those granted per-catalog, only repository will be "*". catalog normally contains the catalog name, but "/" is used for the root catalog.

For example, read access to all repositories in the public catalog is specified (in JSON format) by:

{read: true, write: false, catalog: "public, repository: "*"} 

Whereas read/write access to repository scratch in the root catalog would be:

{read: true, write: true, catalog: "/", repository: "scratch"}

    Which catalog to grant the access on. Leave off or use * to grant access on all catalogs; use / for the root catalog.
  • repository, string (default: *)
    Specifies the repository that access is granted on. Passing * or leaving the parameter off is used to change access for all of the repositories in a catalog.
roles / [NAME] / access delete

Similar to PUT Access but this deletes the read/write access of a user or role.

arguments

  • read, boolean
    Whether to grant read access.
  • write, boolean
    Whether to grant write access
  • catalog, string (default: *)
    Which catalog to grant the access on. Leave off or use * to grant access on all catalogs; use / for the root catalog.

scripts get

Return a list of the names of the scripts stored on the server.

scripts / [PATH*] get

Return the script found at path*

scripts / [PATH*] put

Put a new script in path*.

The body of the request should contain the new script. Scripts whose name ends in .fasl are assumed to be compiled Lisp code (you are responsible for ensuring that it is compatible with the server), anything else is assumed to be raw Common Lisp code, which the server will compile.

scripts / [PATH*] delete

Delete the script at path*.

serverWarnings get

Retrieve any operational warnings from the AllegroGraph server as tuples consisting of a warning identifier tag and descriptive text.

serverWarnings delete

Only a user with superuser access may dismiss warnings.

arguments

  • tag, string
session get

Retrieve information about the currently running sessions.

session post

Starts a new session.

The minilanguage used by the store parameter works as follows:

<store1>
Indicates the triple store named "store1" in the root catalog.
<catalog1:store2>
The triple store "store2" in the "catalog1" catalog.
<http://USER:PASSWORD@HOST:PORT/repositories/REPONAME> <http://USER:PASSWORD@HOST:PORT/catalog/CATNAME/repositories/REPONAME>
A remote store, by URL. If the URL points to the server itself, the store will be opened locally. USER and PASSWORD are not required if the remote server allows for anonymous access to the specified store.
<a> + <b>
The federation of stores "a" and "b".
<a>[rdfs++]
The store "a", with rdfs++ reasoning applied (restriction is also supported as a reasoner type). You can specify the context that inferred triples get using this syntax: <a>[rdfs++#<http://test.org/mycontext>]
<a>{null <http://example.com/graph1>}
Store "a", filtered to only contain the triples in the default graph (null) and the graph named http://example.com/graph1. Any number of graphs can be given between the braces.

This syntax can be composed to created federations of filtered and reasoning stores, for example <http://somehost:10035/repositories/a>{null} + <b>[rdfs++].

The service returns the URL of the new session. Any sub-URLs that were valid under a repository's URL will also work under this session URL. For example, if http://localhost:55555/sessions/7e8df8cd-26b8-26e4-4e83-0015588336ea is returned, you can use http://localhost:55555/sessions/7e8df8cd-26b8-26e4-4e83-0015588336ea/statements to retrieve the statements in the session.

arguments

  • store, string
    A triple-store specification describing the store to open.
  • autoCommit, boolean (default: true)
    Specify whether or not the session should use transactions.
  • lifetime, integer
    The number of seconds the session can be idle before being shutdown and reclaimed.
  • loadInitFile, boolean
    If true, then the initfile will be loaded when the session starts.
  • script, list
    The name of a script file to load; may be specified multiple times.
users get

Returns a list of defined user names.

users / [NAME] put

Create a new user.

Retrieve the read/write access for a user.

This returns a result set, each element of which has a read, write, catalog, and repository component. The first two are booleans, the latter two strings. For permissions granted globally, catalog and repository will have a value of "*", for those granted per-catalog, only repository will be "*". catalog normally contains the catalog name, but "/" is used for the root catalog.

For example, read access to all repositories in the public catalog is specified (in JSON format) by:

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.

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

This returns a list of paths in JSON format where each path is a list of nodes along the path (including the starting and ending nodes). Each node will be either a subject or object of the triples that created the path.

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 or 4 elements each)
  • 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 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.
  • 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 source files will be followed. When true, the caller must have eval permissions.
  • 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.

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.

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
