The EiffelAnnouncementPublishedEvent represents an announcement, technically regarding any topic but typically used to communicate any incidents or status updates regarding the continuous integration and delivery pipeline. This information can then be favorably displayed in visualization and dashboarding applications.
Type: String
Required: Yes
Description: The heading of the announcement.
Type: String
Required: Yes
Description: The body of the announcement.
Type: String
Required: No
Description: A URI where further information can be obtained, if applicable.
Type: String
Required: Yes
Legal values: MINOR, MAJOR, CRITICAL, BLOCKER, CLOSED, CANCELED
Description: The severity of the announcement. The CLOSED and CANCELED values SHOULD only be used when following up a previous announcement, i.e. in conjunction with a MODIFIED_ANNOUNCEMENT link.
This section describes which link types are valid for this event type. For details on how to express the link objects themselves see The Links Object.
Required: No
Legal targets: Any
Multiple allowed: Yes
Description: Identifies a cause of the event occurring. SHOULD not be used in conjunction with CONTEXT: individual events providing CAUSE within a larger context gives rise to ambiguity. It is instead recommended to let the root event of the context declare CAUSE.
Required: No
Legal targets: EiffelActivityTriggeredEvent, EiffelTestSuiteStartedEvent
Multiple allowed: No
Description: Identifies the activity or test suite of which this event constitutes a part.
Required: No
Legal targets: EiffelFlowContextDefinedEvent
Multiple allowed: Yes
Description: Identifies the flow context of the event: which is the continuous integration and delivery flow in which this occurred – e.g. which product, project, track or version this is applicable to.
Required: No
Legal targets: EiffelAnnouncementPublishedEvent
Multiple allowed: No
Description: Identifies an announcement of which this event represents an update or modification, if any. Example usage is to declare the end to a previously announced situation.
Type: String
Format: UUID
Required: Yes
Description: The unique identity of the event, generated at event creation.
Type: String
Format: An event type name
Required: Yes
Description: The type of event. This field is required by the recipient of the event, as each event type has a specific meaning and a specific set of members in the data and links objects.
Type: String
Format: Semantic Versioning 2.0.0
Required: Yes
Description: The version of the event type. This field is required by the recipient of the event to interpret the contents. Please see Versioning for more information.
Type: Integer
Format: UNIX Epoch time, in milliseconds.
Required: Yes
Description: The event creation timestamp.
Type: String[]
Format: Free text
Required: No
Description: Any tags or keywords associated with the events, for searchability purposes.
Type: Object
Required: No
Description: A description of the source of the event. This object is primarily for traceability purposes, and while optional, some form of identification of the source is HIGHLY RECOMMENDED. It offers multiple methods of identifying the source of the event, techniques which may be select from based on the technology domain and needs in any particular use case.
Type: String
Format: Free text
Required: No
Description: Identifies the domain that produced an event.
Type: String
Format: Hostname
Required: No
Description: The hostname of the event sender.
Type: String
Format: Free text
Required: No
Description: The name of the event sender.
Type: String
Format: purl specification
Required: No
Description: The identity of the serializer software used to construct the event, in purl format.
Type: String
Format: URI
Required: No
Description: The URI of, related to or describing the event sender.
Type: Object
Required: No
Description: An optional object for enclosing security related information, particularly supporting data integrity. See Security for further information.
Type: String
Format: Distinguished Name
Required: Yes
Description: The identity of the author of the event. This property is intended to enable the recipient to identify the author of the event contents and/or look up the appropriate public key for decrypting the meta.security.integrityProtection.signature value and thereby verifying author identity and data integrity.
Type: Object
Required: No
Description: An optional object for enabling information integrity protection via cryptographic signing. To generate a correct meta.security.integrityProtection object:
- Generate the entire event, but with the meta.security.integrityProtection.signature value set to an empty string.
- Serialize the event on Canonical JSON Form.
- Generate the signature using the meta.security.integrityProtection.alg algorithm.
- Set the meta.security.integrityProtection.signature value to the resulting signature while maintaining Canonical JSON Form. To verify the integrity of the event, the consumer then resets meta.security.integrityProtection.signature to an empty string and ensures Canonical JSON Form before verifying the signature.
Type: String
Required: Yes
Description: The signature produced by the signing algorithm.
Type: String
Format: A valid JWA RFC 7518 alg parameter value, excluding "none"
Required: Yes
Description: The cryptographic algorithm used to digitally sign the event. If no signing is performed, the meta.security.integrityProtection SHALL be omitted rather than setting meta.security.integrityProtection.alg to "none".
Type: String
Required: No
Description: The producer of the event may include the relevant public key for convenience, rather than relying a separate key distribution mechanism. Note that this property, along with the rest of the event, is encompassed by the integrity protection offered via meta.security.integrityProtection.
Type: Object[]
Required: No
Description: An optional object for enabling verification of intact event sequences in a distributed environment, thereby protecting against data loss, race conditions and replay attacks. It allows event publishers to state the order in which they produce a certain set of events. In other words, it cannot provide any global guarantees as to event sequencing, but rather per-publisher guarantees. Every object in the array represents a named sequence of which this event forms a part. For every event including a given named sequence, the publisher SHALL increment meta.security.sequenceProtection.position by 1. The first event produced in a given named sequence SHALL numbered 1.
Type: String
Required: Yes
Description: The name of the sequence. There MUST not be two identical meta.security.sequenceProtection.sequenceName values in the same event.
Type: Integer
Required: Yes
Description: The number of the event within the named sequence.
Type: String
Format: URI
Required: No
Description: A URI pointing at a location from where the schema used when creating this event can be retrieved. It can be used to parse event data for validation and extraction purposes, for example. Note, that the schema on that URI should be considered immutable.
