--- title: "GetArtifact" method: POST path: "/kythene.v1.KytheneService/GetArtifact" tags: ["kythene.v1.KytheneService"] --- # GetArtifact `POST /kythene.v1.KytheneService/GetArtifact` ## Request - Base URL: `https://kythene.com` (the document declares no server; this is the origin it was published from) - URL: `https://kythene.com/kythene.v1.KytheneService/GetArtifact` - Auth: none required GetArtifact returns artifact metadata, its version history, and optionally the content bytes of one version. ## Headers - `Connect-Protocol-Version` 1, required: Define the version of the Connect protocol - `Connect-Timeout-Ms` number: Define the timeout, in ms ## Request body - KytheneV1GetArtifactRequest - `id` string: id is the artifact's id (from a collection's artifact list). - `includeContent` boolean: include_content adds the content bytes of one version to the response. - `version` integer: version selects which version's content to include; 0 = latest. - `space` string: space optionally selects which of your spaces to act in (an id or name from list_spaces). Omit it when you belong to a single space. ## Response `200` Success - KytheneV1GetArtifactResponse - `artifact` KytheneV1Artifact - `id` string - `name` string - `mime` string - `latestVersion` integer - `latestSize` union - integer - string, int64 - `producer` string - `createdBy` string - `author` string: author names the human who created it (created_by, resolved). - `createdAt` string, date-time: A Timestamp represents a point in time independent of any time zone or local calendar, encoded as a count of seconds and fractions of seconds at nanosecond resolution. The count is relative to an epoch at UTC midnight on January 1, 1970, in the proleptic Gregorian calendar which extends the Gregorian calendar backwards to year one. All minutes are 60 seconds long. Leap seconds are "smeared" so that no leap second table is needed for interpretation, using a [24-hour linear smear](https://developers.google.com/time/smear). The range is from 0001-01-01T00:00:00Z to 9999-12-31T23:59:59.999999999Z. By restricting to that range, we ensure that we can convert to and from [RFC 3339](https://www.ietf.org/rfc/rfc3339.txt) date strings. # Examples Example 1: Compute Timestamp from POSIX `time()`. Timestamp timestamp; timestamp.set_seconds(time(NULL)); timestamp.set_nanos(0); Example 2: Compute Timestamp from POSIX `gettimeofday()`. struct timeval tv; gettimeofday(&tv, NULL); Timestamp timestamp; timestamp.set_seconds(tv.tv_sec); timestamp.set_nanos(tv.tv_usec * 1000); Example 3: Compute Timestamp from Win32 `GetSystemTimeAsFileTime()`. FILETIME ft; GetSystemTimeAsFileTime(&ft); UINT64 ticks = (((UINT64)ft.dwHighDateTime) << 32) | ft.dwLowDateTime; // A Windows tick is 100 nanoseconds. Windows epoch 1601-01-01T00:00:00Z // is 11644473600 seconds before Unix epoch 1970-01-01T00:00:00Z. Timestamp timestamp; timestamp.set_seconds((INT64) ((ticks / 10000000) - 11644473600LL)); timestamp.set_nanos((INT32) ((ticks % 10000000) * 100)); Example 4: Compute Timestamp from Java `System.currentTimeMillis()`. long millis = System.currentTimeMillis(); Timestamp timestamp = Timestamp.newBuilder().setSeconds(millis / 1000) .setNanos((int) ((millis % 1000) * 1000000)).build(); Example 5: Compute Timestamp from Java `Instant.now()`. Instant now = Instant.now(); Timestamp timestamp = Timestamp.newBuilder().setSeconds(now.getEpochSecond()) .setNanos(now.getNano()).build(); Example 6: Compute Timestamp from current time in Python. timestamp = Timestamp() timestamp.GetCurrentTime() # JSON Mapping In JSON format, the Timestamp type is encoded as a string in the [RFC 3339](https://www.ietf.org/rfc/rfc3339.txt) format. That is, the format is "{year}-{month}-{day}T{hour}:{min}:{sec}[.{frac_sec}]Z" where {year} is always expressed using four digits while {month}, {day}, {hour}, {min}, and {sec} are zero-padded to two digits each. The fractional seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution), are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone is required. A proto3 JSON serializer should always use UTC (as indicated by "Z") when printing the Timestamp type and a proto3 JSON parser should be able to accept both UTC and other timezones (as indicated by an offset). For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past 01:30 UTC on January 15, 2017. In JavaScript, one can convert a Date object to this format using the standard [toISOString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString) method. In Python, a standard `datetime.datetime` object can be converted to this format using [`strftime`](https://docs.python.org/2/library/time.html#time.strftime) with the time format spec '%Y-%m-%dT%H:%M:%S.%fZ'. Likewise, in Java, one can use the Joda Time's [`ISODateTimeFormat.dateTime()`]( http://joda-time.sourceforge.net/apidocs/org/joda/time/format/ISODateTimeFormat.html#dateTime() ) to obtain a formatter capable of generating timestamps in this format. - `updatedAt` string, date-time: A Timestamp represents a point in time independent of any time zone or local calendar, encoded as a count of seconds and fractions of seconds at nanosecond resolution.

Labels of who currently approves / rejects. - `rejectedBy` string[] - `staleReviews` integer - `blocks` KytheneV1Block[]: Block-level review (app#75-78): the artifact's rendered blocks, each with a stable anchor + text + current status, when the artifact is under review (a collection has requested review); empty otherwise. Use these anchors with review_block. - `anchor` string: anchor is the stable identity - address a block by this in review_block. - `text` string: text is the block's normalised content (what to read / quote). - `kind` string: kind is heading | paragraph | list_item | blockquote | code | table. - `ordinal` integer - `status` string: status is "" when unflagged, else one of: needs_review (look again), needs_work (changes required), done (action complete), approved (signed off), reject_remove (should be removed). set_by is "human" or "instance" (who judged it). changed_since = the block was edited after it was last flagged. - `setBy` string - `changedSince` boolean - `annotationId` string: annotation_id identifies the review thread on this block, when flagged. Use it in review_block to address a thread whose block was REWRITTEN (its anchor no longer resolves) - the only way to close or reply to it. Empty when unflagged. - `rewritten` boolean: rewritten is true for a thread whose block was edited away: it has no live block, `text` is what the comment originally referred to, and it is addressable only by annotation_id. ## Other responses - `default`: Error --- [API](https://skmtc.dev/kythene/apis/kythene-v1.md) · [All operations](https://skmtc.dev/kythene/apis/kythene-v1/llms.txt) · [OpenAPI document](https://skmtc.dev/kythene/apis/kythene-v1/revisions/5a768e642d10?raw)
