Import general XML schema. An error element containing information about the error. A single pulse, or a set of pulses which are not directly connected (in other words not a chain or a skipList). A sequence of pulses with none missing (all the pulses between time T1 and T2). A list of pulses in chronological order within a chain; the pulses in the list are chained using the field "outputValue". A type for a beacon error response. A short error code. Type for a locale specific error description. The type for a single pulse. The URI which identifies the pulse as it was originally released; May also be used to retrieve this pulse. The version string, e.g. "0.1.0". The cipherSuite used to identify the hash and signing algorithms. Currently defined value: 0 - SHA512 hashing and RSA signatures with PKCSv1.5 padding The time interval, in milliseconds, between expected pulses. The SHA-512 hash of the X.509 ASN.1 encoding of the certificate containing the public key which can be used to verify this pulse. The index (starting with one) of the chain that a pulse is contained in. A positive integer, equal to 1 for the first pulse in a chain, and incremented by 1 for each consecutive pulse within a chain. A time string formatted according to the rules of RFC 3339 (https://www.ietf.org/rfc/rfc3339.txt); all date/times must use UTC time denoted by 'Z' suffix with no local timezone adjustment. A random value represented as a 64-byte (512 bits) hex string. The SHA-512 hash of a value that can be obtained externally to the Beacon, whose generation is outside the control of the operators of the beacon, and whose value is unpredictable to anyone before a specified time of its use in this field; additionally, it is desirable that these values are places on an external archive that ensures integrity and availability. The SHA-512 hash value of a description of the external source. The status code for retrieval of a value from the source. A SHA-512 hash of a value as described in sourceId. The SHA-512 hash value of a pulse represented as a 64-byte hex string. the type of list value: previous - the previous pulse value, or 0's if no such pulse exists; hour - the outputValue of the first pulse of the UTC "hour" of the previous pulse, or 0's if no such pulse exists; day - the outputValue of the first pulse of the UTC "day" of the previous pulse, or 0's if no such pulse exists; month - the outputValue of the first pulse of the UTC "month" of the previous pulse, or 0's if no such pulse exists; year - the outputValue of the first pulse of the UTC "year" of the previous pulse, or 0's if no such pulse exists. The URI of the Pulse. The SHA-512 hash of the next localRandomValue (a pre-commitment) as a 64-byte hex string; this value may be all '0's if not used. The status code value: 0 - Chain intact, values all good; 1 - Start of a new chain of values, previous hash value will be all zeros; 2 - Time between values is greater than the period, but the chain is still intact; 3 - Time between values is greater than the period, the chain is intact, but the input of the prior precommitmentValue was lost. A big-endian hex encoded digital signature using the public key contained in certificateId computed over the SHA-512 hash of (in order): bytelen(uri); uri as a UTF-8 encoded sequence of bytes; bytelen(version); version as a UTF-8 encoded sequence of bytes; cipherSuite as a 4-byte big-endian integer value; period as a 4-byte big-endian integer value; length(certificateId); certificateId as a hex-decoded sequence of bytes; chainIndex as an 8-byte big-endian integer value; pulseIndex as an 8-byte big-endian integer value; bytelen(timestamp); timestamp as a UTF-8 encoded sequence of bytes; length(localRandomValue); localRandomValue as a hex-decoded sequence of bytes; length(external/sourceId); external/sourceId as a hex-decoded sequence of bytes; external/statusCode as a 4-byte big-endian integer value; length(external/value); external/value as a hex-decoded sequence of bytes; length(listValue[@type=’previous’]); listValue[@type=’previous’] as a hex-decoded sequence of bytes; length(listValue[@type=’hour’]); listValue[@type=’hour’] as a hex-decoded sequence of bytes; length(listValue[@type=’day’]); listValue[@type=’day’] as a hex-decoded sequence of bytes; length(listValue[@type=’month’]); listValue[@type=’month’] as a hex-decoded sequence of bytes; length(listValue[@type=’year’]); listValue[@type=’year’] as a hex-decoded sequence of bytes; length(precommitmentValue); precommitmentValue as a hex-decoded sequence of bytes; statusCode as a 4-byte big-endian integer value. Note: bytelen(x) returns the number of bytes in the UTF-8 encoded String x; length(x) returns the number of bytes after x has been hex decoded; the result of both bytelen(x) and length(x) are encoded as 4-byte big-endian integer values; different listValue types may be used, but if provided, they must be included in the hash in the order they are provided. A 64-byte hex string of the SHA-512 hash of the concatenation of the input into the signatureValue and the hex decoded signatureValue as a sequence of bytes concatenated in that order and then hashed. A type for a sequence of pulses. The type of listValue; see documentation in pulseType for more information.
