Query Service#

Changed in version 2.0.

ESS provides a Query service that allows a Pod Owner (or other agents with Control access to the Pod) to query RDF (Resource Description Framework) data in the Pod. Specifically, the ESS Query service provides a Quad Pattern Fragment (QPF) interface that the Pod Owner (or other agents with Control access to the Pod) can use to query RDF data.

See also:

QPF Query Service#

ESS Query service has the following QPF endpoint:

https://fragments.{ESS DOMAIN}/qpf

Query Parameters#

To query a Pod using QPF, you can specify the following query parameters to the service as part of a GET operation:

?storage={POD}&subject={SUBJECT}&predicate={PREDICATE}&object={OBJECT}&graph={GRAPH}

Tip

The Query service includes the Hypermedia Control as part of every result set. You can issue a GET to the service with only the storage parameter set (i.e., omit the data matching pattern parameters) to return just the Hypermedia Control.

The Hypermedia Control provides the supported query template and mapping of the QPF quad pattern selector parameters for querying data.

The table of parameters is provided below to complement the returned Hypermedia Control information. However, Hypermedia Control acts as the definitive source.

Parameter

Description

storage

Required. URL of the Pod to query.

URL-encode the value.

If the storage parameter is omitted, ESS Query service returns a 400 Bad Request.

Note

  • storage is an ESS-specific parameter.

  • The querying agent must be either the Pod Owner or another agent with Control access to the Pod.

subject

The subject to match, as defined in the QPF quad pattern selector.

Triples with blank node values will be normalized into statements with URIs.

URL-encode the value.

predicate

The predicate to match, as defined in the QPF quad pattern selector.

URL-encode the value.

object

The object to match, as defined in the QPF quad pattern selector.

URL-encode the value.

graph

The graph (the URL of the Resource) to match, as defined in the QPF quad pattern selector.

URL-encode the value.

Query Response#

Important

The query results may lag behind the current state of the Resource. For more details, see Query Service Indexer.

The response includes:

                 ] .

For more information, see Hypermedia controls in the QPF specification.

Metadata#

Per the Quad Pattern Fragment (QPF) specification, a successful query response includes the metadata.

The returned metadata includes:

Matching Data Results#

Note

  • ESS Query service only returns matching data from the data that has been indexed.

  • Because the resource indexing occurs after the indexer consumes a resource change notification event, the query results may lag behind the current state of the Resource.

A successful query response includes the matching data in triples.

For example,

<https://storage.example.com/a211ad26-zzzz-9999-8b20-acb3aed0e369/readingLists/myList> {
    <https://storage.example.com/a211ad26-zzzz-9999-8b20-acb3aed0e369/readingLists/myList#title2>

            rdf:type  <https://www.w3.org/ns/activitystreams#Article> .
}

The number of query results returned per page is determined by INRUPT_FRAGMENTS_PAGE_SIZE). For pagination information, see Metadata.

Query Service Indexer#

To query your data, the Query service uses an indexer to index your RDF resources; i.e., the the Query service returns results only from the indexed RDF resources. For more information on the indexer, see Query Service Indexer.

Access Control#

UMA and Solid-OIDC Access Tokens#

For query access to the Pod, the ESS’ Query service can use either:

  • UMA token, or

  • Solid-OpenID Connect (OIDC) access token.

With the UMA authorization flow:

  1. When you issue your query without an access token, the Query service returns a 401 along with a ticket and authorization server in the WWW-Authenticate header.

  2. From the authorization server, the client can exchange the UMA ticket for the UMA access token.

    • To exchange the UMA ticket for the access token, the client must include its client_id.

  3. Include the access token in the header of your query request and retry.

See also:

Querying Agent#

Only Agents who have Control Read access to the root of the Pod, such as the Pod Owner, can access data from the QPF endpoint.

You can further specify which applications can query the endpoint by granting specific applications appropriate access.

Indexer#

To index the data in a resource, indexer requires Read access to the resource. The Query service only returns results from the indexed RDF resources.

See also:

Configuration#

As part of the installation process, Inrupt provides base Kustomize overlays and associated files that require deployment-specific configuration inputs.

The following configuration options are available for the service and may be set as part of updating the inputs for your deployment. The Inrupt-provided base Kustomize overlays may be using updated configuration values that differ from the default values.

Query Service Configuration#

INRUPT_FRAGMENTS_PAGE_SIZE#

Default: 10

The number of matching results per page.

QUARKUS_LOG_LEVEL#

Default: INFO

Logging level.

UMA Configuration#

INRUPT_AUTHZ_AS_URI#

The URI of the UMA Authorization Server.

The value must match:

INRUPT_JWT_AUTHORIZATION_SERVER_ISSUER#

The URI of the UMA token issuer.

The value must match INRUPT_AUTHZ_AS_URI.

INRUPT_JWT_AUTHORIZATION_SERVER_JWKS#

The JWKS endpoint of the INRUPT_JWT_AUTHORIZATION_SERVER_ISSUER.

OIDC Configuration#

INRUPT_JWT_ALLOWED_SIGNATURE_ALGORITHMS#

Default: ES256, RS256

A comma-separated list that specifies the allowed encryption algorithms used to sign ID tokens.

INRUPT_JWT_ISSUER_ALLOW_LIST#

A comma-separated list [1] of trusted issuers of Solid-OIDC tokens.

See also INRUPT_JWT_ISSUER_DENY_LIST.

Tip

Ensure that ESS UMA service’ INRUPT_JWT_ISSUER_ALLOW_LIST is consistent with the INRUPT_JWT_ISSUER_ALLOW_LIST value set for this service.

INRUPT_JWT_ISSUER_DENY_LIST#

A comma-separated list [1] of disallowed issuers of Solid-OIDC tokens.

Tip

Ensure that ESS’ UMA service’s INRUPT_JWT_ISSUER_DENY_LIST is consistent with the INRUPT_JWT_ISSUER_DENY_LIST value set for this service.

Kafka Configuration#

INRUPT_KAFKA_AUDITV1EVENTSENCRYPTED_CIPHER_PASSWORD#

The strong cipher key to use when running auditing with encrypted messages over the auditv1eventsencrypted topic.

INRUPT_KAFKA_AUDITV1EVENTSPRODUCERENCRYPTED_CIPHER_PASSWORD#

The strong cipher key to use when running auditing with encrypted messages over the auditv1eventsproducerencrypted topic.

Added in version 2.2.0.

KAFKA_BOOTSTRAP_SERVERS#

Default: localhost:9092

Comma-delimited list of Kafka broker servers for use by ESS services.

Setting KAFKA_BOOTSTRAP_SERVERS configures ESS to use the same Kafka instance(s) for all its Kafka message channels (e.g., solidresource and auditv1out message channels). The UMA service uses the auditv1out message channel.

Note

Inrupt-provided overlays default to using KAFKA_BOOTSTRAP_SERVERS.

To use a different Kafka instance for the auditv1out channel, use specific message channel configuration.

See also ESS’ Kafka Configuration.

Configuration Logging#

Starting in 2.2, ESS services log their startup configuration.

INRUPT_LOGGING_CONFIGURATION_PREFIX_ALLOW#

Default: inrupt,smallrye.jwt.expiration.grace,mp.jwt.verify.clock.skew,smallrye.jwt.always-check-authorization,smallrye.jwt.token.decryption.kid,smallrye.jwt.token.schemes,smallrye.jwt.require.named-principal,smallrye.jwt.time-to-live,smallrye.jwt.jwks.refresh-interval,smallrye.jwt.jwks.forced-refresh-interval,smallrye.jwt.required.claims,mp.jwt.verify.audiences

A comma-separated list of configuration property prefixes (case-sensitive) that determine which configurations are logged:

When specifying the prefixes, you can specify the prefixes using one of two formats:

Warning

Use the same format for both INRUPT_LOGGING_CONFIGURATION_PREFIX_ALLOW and INRUPT_LOGGING_CONFIGURATION_PREFIX_DENY.

For example, if you change the format of INRUPT_LOGGING_CONFIGURATION_PREFIX_ALLOW, change the format of INRUPT_LOGGING_CONFIGURATION_PREFIX_DENY as well.

Tip

To avoid allowing more than desired configurations, specify as much of the prefix as possible. If the prefix specifies the complete prefix term, include the term delineator. For example:

  • If using dot-notation, if you want to match configuration properties of the form foobar.<xxxx>..., specify foobar. (including the dot .) instead of, for example, foo or foobar.

  • If using converted form, if you want to match configuration properties of the form FOOBAR_<XXXX>..., specify FOOBAR_ (including the underscore _) instead of, for example, FOO or FOOBAR.

Added in version 2.2.0.

INRUPT_LOGGING_CONFIGURATION_PREFIX_DENY#

Default: inrupt.kafka

A comma-separated list of configuration name prefixes (case-sensitive) that determines which configurations (that would otherwise match the INRUPT_LOGGING_CONFIGURATION_PREFIX_ALLOW) are not logged. That is, INRUPT_LOGGING_CONFIGURATION_PREFIX_DENY acts as a filter on INRUPT_LOGGING_CONFIGURATION_PREFIX_ALLOW. For example:

  • If foobar. is an allowed prefix, to suppress foobar.private.<anything>, you can specify foobar.private. to the deny list.

  • If foobar. is not an allowed prefix, no property starting with foobar. is logged. As such, you do not need to specify foobar.private to the deny list.

When specifying the prefixes, you can specify the prefixes using one of two formats:

Warning

Use the same format for both INRUPT_LOGGING_CONFIGURATION_PREFIX_ALLOW and INRUPT_LOGGING_CONFIGURATION_PREFIX_DENY.

For example, if you change the format of INRUPT_LOGGING_CONFIGURATION_PREFIX_ALLOW, change the format of INRUPT_LOGGING_CONFIGURATION_PREFIX_DENY as well.

Added in version 2.2.0.

Logging Redaction#

INRUPT_LOGGING_REDACTION_NAME_ACTION#

Default: REPLACE

Type of the redaction to perform. Supported values are:

Action

Description

REPLACE

Default. Replaces the matching text with a specified replacement.

PLAIN

Leaves the matching field unprocessed. Only available if the redaction target is a field (i.e., INRUPT_LOGGING_REDACTION_{NAME}_FIELD).

DROP

Suppresses the matching field. Only available if the redaction target is a field (i.e., INRUPT_LOGGING_REDACTION_{NAME}_FIELD).

PRIORITIZE

Changes the log level of the matching message.

SHA256

Replaces the matching text with its hash.

  • If the action is REPLACE (default), see also INRUPT_LOGGING_REDACTION_{NAME}_REPLACEMENT.

  • If the action is to PRIORITIZE, see also INRUPT_LOGGING_REDACTION_{NAME}_LEVEL.

For more information on log redaction, see Logging Redaction.

Added in version 2.2.0.

Application-Defined Metadata Propagation#

INRUPT_AUDIT_PRODUCER_REQUEST_METADATA_ALLOW#

A comma-separated list [1] of application-defined properties that can be included in the associated audit events (unless specified in the corresponding INRUPT_AUDIT_PRODUCER_REQUEST_METADATA_DENY).

This configuration is case-sensitive to the propagated properties in the baggage.

Tip

To include a propagated property that was added via the INRUPT_REQUEST_METADATA_PROPAGATOR_HEADER_ALLOW configuration, ensure that the cases of these properties match.

See:

Added in version 2.2.0.

INRUPT_AUDIT_PRODUCER_REQUEST_METADATA_DENY#

A comma-separated list [1] of application-defined properties to exclude from the associated audit messages. This setting takes precedence over INRUPT_AUDIT_PRODUCER_REQUEST_METADATA_ALLOW.

This configuration is case-sensitive to the propagated properties in the baggage.

Tip

To exclude a propagated property that was added via the INRUPT_REQUEST_METADATA_PROPAGATOR_HEADER_ALLOW configuration, ensure that the cases of these properties match.

See:

Added in version 2.2.0.

INRUPT_LOGGING_REQUEST_METADATA_ALLOW#

A comma-separated list [1] of application-defined properties that can be included in the associated log messages (unless specified in the corresponding INRUPT_LOGGING_REQUEST_METADATA_DENY).

This configuration is case-sensitive to the propagated properties in the baggage.

Tip

To include a propagated property that was added via the INRUPT_REQUEST_METADATA_PROPAGATOR_HEADER_ALLOW configuration, ensure that the cases of these properties match.

See:

Added in version 2.2.0.

INRUPT_LOGGING_REQUEST_METADATA_DENY#

A comma-separated list [1] of application-defined properties to exclude from the associated log messages. This setting takes precedence over INRUPT_LOGGING_REQUEST_METADATA_ALLOW.

This configuration is case-sensitive to the propagated properties in the baggage.

Tip

To exclude a propagated property that was added via the INRUPT_REQUEST_METADATA_PROPAGATOR_HEADER_ALLOW configuration, ensure that the cases of these properties match.

See:

Added in version 2.2.0.

INRUPT_REQUEST_METADATA_PROPAGATOR_HEADER_ALLOW#

A comma-separated list [1] of non-baggage request headers to add to the baggage (unless specified in the corresponding INRUPT_REQUEST_METADATA_PROPAGATOR_HEADER_DENY); i.e., include these non-baggage request headers as application-defined properties.

The configuration is case-insensitive; i.e., the listed headers do not need to match the case of the client request headers. For example, a list that includes x-correlation-id can match x-correlation-id header, X-CoRrElAtIoN-Id header, etc.

See:

Added in version 2.2.0.

INRUPT_REQUEST_METADATA_PROPAGATOR_HEADER_DENY#

A comma-separated list [1] of non-baggage request headers to exclude from being added to the baggage; i.e., excludes these headers as application-defined properties. This setting takes precedence over INRUPT_REQUEST_METADATA_PROPAGATOR_HEADER_ALLOW.

The configuration is case-insensitive; i.e., the listed headers do not need to match the case of the client request headers. For example, a list that includes x-correlation-id can match (and exclude) x-correlation-id header, X-CoRrElAtIoN-Id header, etc.

See:

Added in version 2.2.0.

INRUPT_REQUEST_METADATA_PROPAGATOR_HEADER_OVERRIDES#

A flag that determines ESS behavior when metadata property is defined both as a header and as a baggage entry:

  • If true, ESS updates/overrides the baggage entry with the header value.

  • If false (the default), ESS keeps the baggage entry.

For details, Duplicate Property Definition.

Added in version 2.2.0.

INRUPT_REQUEST_METADATA_REFLECTOR_HEADER_ALLOW#

A comma-separated list [1] of application-defined properties that can return as response headers (unless specified in the corresponding INRUPT_REQUEST_METADATA_REFLECTOR_HEADER_DENY).

This configuration is case-sensitive to the propagated properties in the baggage.

Tip

See:

Added in version 2.2.0.

INRUPT_REQUEST_METADATA_REFLECTOR_HEADER_DENY#

A comma-separated list [1] of application-defined properties to exclude from returning as response headers. This setting takes precedence over INRUPT_REQUEST_METADATA_REFLECTOR_HEADER_ALLOW.

This configuration is case-sensitive to the propagated properties in the baggage.

Tip

To exclude a propagated property that was added via the INRUPT_REQUEST_METADATA_PROPAGATOR_HEADER_ALLOW configuration, ensure that the cases of these properties match.

Added in version 2.2.0.

Purge Configuration#

The Query service contains user data, and as such it can be purged upon user request. See the Purger Application documentation for more information about the data being purged.

INRUPT_PURGE_BATCH_SIZE#

Default: 100

The maximum number of records that the purge task will purge in each batch. This must be a non-zero, positive integer.

Added in version 2.3.0.

INRUPT_PURGE_CLEANUP_TASK_EVERY#

Default: PT5H

Frequency at which a task goes through stored purge statuses to clear any which are beyond their retention window.

Added in version 2.3.0.

INRUPT_PURGE_IN_PROGRESS_TIMEOUT_SECONDS#

Default: 120

Timeout after which an ongoing purge task is considered stale. Stale tasks are picked up by an ESS background process to be taken to completion. By keeping track of a purge task’s state (active or stale) the service can ensure that a purge which was started will eventually reach completion, even if the system is disrupted whilst the asynchronous purge process is ongoing.

Added in version 2.3.0.

INRUPT_PURGE_PROCESS_TASK_EVERY#

Default: PT5M

Frequency at which an ESS background process goes through ongoing purges to pick up the incomplete stale ones. See INRUPT_PURGE_IN_PROGRESS_TIMEOUT_SECONDS for additional details.

Added in version 2.3.0.

INRUPT_PURGE_STATUS_RETENTION_WINDOW#

Default: P2D

Duration after which a purge task status will be cleared from storage. The purge task contains some Personally Identifying Data (such as the WebID), so ensuring it is cleared after a purge is required for compliance.

Added in version 2.3.0.
