Configuration properties in alphabetical order

Configuration properties for Ontoserver can be used by including them in the (environment) section of the (ontoserver) container, within the (docker-compose.yml) file described here.

atom.preload.feedLocation (file:///data/preload.xml)
Location/s for Atom feeds whose entries will be fetched into Ontoserver on startup. For more information see Preload Configuration.
atom.preload.feedLocation.default (classpath:preload/ontoserver-profiles.xml,classpath:preload/ncts-profiles.xml)
Location/s for Atom feeds whose entries will be fetched into Ontoserver on startup as default resources (this includes default profiles for resources). This parameter should be only modified to deliberately exclude the default profiles. For more information see Preload Configuration.
atom.preload.schedule.cron ()
If set to a valid cron expression, the server will re-execute preload at the schedule specified by the cron expression. If this property is not present the schedule is disabled, which is the default.

Crontab expression are a list of six single space-separated fields: representing second, minute, hour, day, month, weekday. Month and weekday names can be given as the first three letters of the English names.

Example expressions
"0 0 * * * *" The top of every hour of every day.
"*/10 * * * * *" Every ten seconds.
"0 0 8-10 * * *" 8, 9 and 10 o'clock of every day.
"0 0 6,19 * * *" 6:00 AM and 7:00 PM every day.
"0 0/30 8-10 * * *" 8:00, 8:30, 9:00, 9:30, 10:00 and 10:30 every day.
"0 0 9-17 * * MON-FRI" on the hour nine-to-five weekdays
"0 0 0 25 12 ?" every Christmas Day at midnight
atom.syndication.disableChecksums (false)
If true, tells Ontoserver not to check that the Syndication feed checksums match when obtaining and processing an entry.
atom.syndication.excludeLength (false)
If true then omit the length attribute from the link elements (for locally generated entries) of the Syndication Feed. If your feed includes large Resources, then this can speed up feed generation time.
atom.syndication.excludeXml (false)
If true, then omit XML versions of locally syndicated FHIR Resources from the downstream feed. If your feed includes large Resources, then this can significantly speed up feed generation time.
atom.syndication.publish.enabled (false)
if true, enables the downstream Syndication endpoint.
atom.syndication.publish.feedTitle (Ontoserver® Syndication Feed)
Title to use for the downstream Syndication feed.
atom.syndication.feedLocation (https://api.healthterminologies.gov.au/syndication/v1/syndication.xml)
Comma-separated list of URI-encoded absolute URLs of the upstream Syndication feeds. By default, this points to the Australian NCTS Syndication Service (note that this service requires credentials). Minimum is that embedded , and % characters in the URLs must be %-encoded
atom.syndication.publish.fhir.enabled (false)
If downstream syndication is also enabled, then true will ensure that all FHIR Terminology Resources are included in the downstream feed, or selected will mean that all resources will be included that have been marked for syndication using /synd/setSyndicationStatus
atom.syndication.publish.fhir.secureSyndicated (false)

Setting this config to true will require SYND_WRITE (in addition to FHIR_WRITE) in order to update or delete a FHIR resource that has been selected for syndication using setSyndicationStatus.

atom.syndication.publish.index.enabled (selected)
If downstream syndication is also enabled, then true will ensure that all CodeSystem binary indexes are included in the downstream feed, or selected will mean that all indexes will be included that have been marked for syndication using /synd/setSyndicationStatus
atom.syndication.republishUpstreamEntries (false)
If true, and atom.syndication.publish.enabled is also enabled, then includes all the upstream Syndication feed entries in the downstream feed.
atom.syndication.republishUpstreamFeeds
If specified, entries from these feeds will be republished instead of entries from atom.syndication.feedLocation. This option is only considered if atom.syndication.publish.enabled and atom.syndication.republishUpstreamEntries are both enabled.
atom.syndication.timeout.ms (16000)
How long to wait before aborting the request for the upstream Syndication feed.
atom.syndication.client.connectTimeout (10000)
Sets the connection timeout for downloading feeds and data from syndication feeds

The audience to use when validating JWT tokens. Particularly useful when one authorisation server/realm with a single signing key is used across multiple Ontoserver instances. In that instance audience validation allows Ontoserver instances to determine whether a presented token (and its contained claims) are intended for that specific Ontoserver instance or not. The default value if not set is blank, which means that the aud claim will not be checked. If set, requests will be rejected if the aud claim of the presented JWT token does not match this value. The usual convention for this value is the base URL or host name of the Ontoserver instance.
ontoserver.security.enabled (false)
If true, enables role-based security on the various Ontoserver API families. Each of the api, fhir, and synd endpoints has separate READ and WRITE roles.
ontoserver.security.hsts (true)
If false, then the Strict-Transport-Security header will not be sent for HTTPS responses.
ontoserver.security.readOnly.api (false)
If true, and role-based security is enabled, then all users (including unauthenticated users) get minimum of READ access to the api endpoint.

The secret signing key for the JWT tokens that allows Ontoserver to trust the tokens produced by your authorization server. See the Security Configuration page for more detail.
ontoserver.security.verify.certs (true)
If false, turns off checking of SSL certificates.
ontoserver.synd.base
Base URL for the downstream Syndication API. Set this explicitly if the auto-detected value is wrong (e.g., when your server is sitting behind an API Gateway / Load Balancer / Proxy Server) This affects syndication.xml as well as full URLs in for downloading binary indexes (URLs for downloading syndicated FHIR resources are affected by ontoserver.fhir.base.
ontoserver.well-known.openid-configuration
URL for openid-configuration details. May be set to point to the openid-configuration endpoint for an OpenID server so that Ontoserver will pass on the contents when .well-known/smart-configuration is requested.
snomed.default.edition (32506021000036107)
Default SNOMED CT Edition to use when a SNOMED CT version is not supplied. 32506021000036107 corresponds to the Australian Edition of SNOMED CT
snomed.implicit.map[n]. ...
Allows specification of metadata to enable SNOMED CT simple map reference sets as FHIR implicit ConceptMaps. To respond to ConceptMap $translate requests FHIR requires relationship types (equivalent, relatedto etc), and a target code system URI in responses. However SNOMED CT's simple map reference set does not include either of these pieces of required information, relying on users of the simple map type reference sets to know these details from documentation or implicitly. Therefore to support implicit ConceptMap $translate operations, Ontoserver provides configuration parameters to supply this information, and if supplied will enable implicit ConceptMap $translate operations for the specified reference set identifier.

Ontoserver includes the following configuration for two simple map type reference sets in its base configuration:

# Implicit maps - CTV3
snomed.implicit.map[0].refset=900000000000497000
snomed.implicit.map[0].equivalence=equivalent
snomed.implicit.map[0].target-column=0
snomed.implicit.map[0].system=http://read.info/ctv3

# Implicit maps - Inactivation indicator
snomed.implicit.map[1].refset=900000000000489007
snomed.implicit.map[1].equivalence=relatedto
snomed.implicit.map[1].target-column=0
snomed.implicit.map[1].system=http://snomed.info/sct

These can serve as templates for adding configuration for additional simple map reference sets. Note that this configuration may only be completely restated starting from index 0, it cannot be appended to starting from index 2. I.e. if adding configuration it must start with snomed.implicit.map[0] and restate the above two sets of configuration if retaining support for these simple map type reference sets is desired.

snomed.refset.fieldNames.{refsetId} ...
Allows specification of metadata to document the additional column fieldNames as used in the RF2 file for the specified reference set. That is, columns 7 and greater.

For example, the following would specify the field names of the SubstanceToSnomedCtauMappingSubstance to SNOMED CT-AU mapping reference set.

snomed.refset.fieldNames.281000036105=mapType,targetSnomedCtSubstance
