This standard defines the Main Profileof the Music Licensing Companies Message Suite Standard (MLC). DDEX may, over time, develop Business Profiles of this standard. Messages created in accordance with such Business Profiles are expected to be largely compatible with this Main Profile standard. Any organisation wishing to implement this (or any other DDEX Standard) is required to apply for an Implementation Licence. The terms of the licence and an application form can be found at http://www.ddex.net/implementation/form.html.
Clause 6 defines the choreography buy which the messages defined in this Standard are to be exchanged. Clauses 7 and 8 then provide the message content: Clause 7 provides an informative overview whereas Clause 7 normatively specifies all elements of all messages within this Standard, and their descriptions as they appear in the DDEX Data Dictionary.
Annex B, contained in a separate document, provides the relevant XML Schema files. The normative clauses of this document, including Annex A, should be read together to form the Music Licensing Company Message Suite Standard.
Version 1.1 provides support for legacy territories and TIS territory codes as well as the ability to communicate the same richness in performer information as is possible in the Release Notification Message Suite Standard.

4 Terms and Abbreviations
For the purposes of this Standard, the following terms should be read as having the meanings specified here:
A grouping of one or more DDEX Messages to be processed by the recipient together.
An entity in a DDEX Message that has the technical cardinality of 0-1 or 0-n but that is mandatory when a DDEX message is sent in a specific commercial context.
Contractually Mandatory fields may, however, be mandatory when a DDEX message is sent in a specific commercial context. In such circumstances, a message is deemed conformant only if and when it contains all the “contractually mandatory” fields as agreed by Message Sender and Message Recipient.
Music Licensing Company
A company that is duly authorised to issue licences for the use of SoundRecordings and music videos. Music Licensing Companies may issue licences on behalf of phonogram producers, performers or both.
Note: Music Licensing Companies were previously referred to as Producers (and/or Performers) Collection Societies (PCSs).
A Manifestation of a Release (or another Resource) which is made available to Consumers, by sale, loan or other means. The attributes of a Release in its digital manifestation as a Product may be technical (e.g., the codec or bit rate); a mode of distribution (e.g., downloading or streaming); or a commercial term (e.g., price).
A Release is an abstract entity representing a bundle of one or more Resources compiled by an Issuer. The Resources in Releases are normally primarily sound recordings or music audio-visual recordings, but this is not invariably the case. The Release is not itself the item of trade (or “Product”). Products have more extensive attributes than Releases; one Release may be disseminated in many different Products.
Release Creator is an organisation which is the owner of copyrights in sound and/or music audiovisual recordings and/or exclusive licensees of copyrights in sound and/or music audiovisual recordings.
A digital fixation of an expression of an abstract Work (such as a sound recording, a video, an image, software or a passage of text). Resources are individual assets that make up a Release. Typical Resources are sound recordings, video clips and cover art images.

5 Message Overview
All messages defined in this standard make intensive use of allowed-value sets. These allowed value sets are shared between all DDEX standards and DDEX provides a XML Schema Definition file for all of these allowed values. These values are also contained in the DDEX Data Dictionary available from ddex.net.
The full namespace for the XML Schema document for the allowed-value sets is
DDEX may regularly extend this list of allowed-value sets. Any such extensions to this list are issued on a date later than the date on which this Standard is issued form part of this Standard. Thus the list of allowed-value sets provided Annex A contains the list of allowed-value sets valid on the data of issuance of this Standard.
6 Message Choreography
The exchange of messages defined in this standard shall be exchange using the ftp mode defined in Clause 7 of the Automated Message Exchange Protocol Standard. The sender of a message shall place all messages that comprise a Batch into a single folder on the ftp server.
To ensure sequential processing, a Batch is identified by the date and time of its creation in the form YYYYMMDDhhmmssnnn with
YYYY being the year of Batch creation;
MM being the month of Batch creation;
DD being the day of Batch creation;
hh being the hour of Batch creation;
mm being the minute of Batch creation;
ss being the second of Batch creation; and
nnn being the millisecond of Batch creation.
Each message sent in the Batch shall be named as follows: MMMM_SSSSS.xml with
MMMM being the name (root tag) of the Message; and
SSSSS being a zero padded serial number within that batch.
manifest.xmland shall be placed into the same folder as all other files.
Its syntax is defined in Clause 8.8 and shown below:
Once the Message recipient has downloaded all files of the Batch, the recipient shall upload an Acknowledgement file. The acknowledgement file shall be called acknowledement.xml and shall be placed into the same folder as all other files.
Its syntax is defined in Clause 9.3 of the Automated Message Exchange Protocol Standard and shown below:
The Table below summarises the point in the Release cycle when each message is sent. The table also indicates who sends which message to whom and which of the messages are defined in this Standard.
|Message Name||Initiating Event|
|1||RequestSoundRecordingInformationMessage||A MLC has received sales information about a SoundRecordings but has not received any information, including rights claims, with respect to that SoundRecordings. Such information can be requested.|
The MLC then forwards information about theses Releases and mandated uses to a second MLC in each mandated territory (however, this message can also be sent proactively, i.e. not in response to a RequestSoundRecordingInformationMessage).
Update with the intention that the receiving MLC deletes – or marks inactive – the listed SoundRecordingRightsClaims.
After sales of sound carriers or Releases for the mandated territories have been received and processed by a MLC, some sales information needs to be shared with sister MLCs in the mandated territories, for those MLCs that allocate revenues on the basis of unit sales
After invoicing the user, payment by the user to the MLC, and the allocation by MLC of the related revenues to SoundRecordings, the MLC declares to another MLC its share in the revenues

Figure 3 — Choreography of the Main Profile of the Music Licensing Company Message Suite
The communication between Record Companies and Music Licensing Companies is not defined in this version of the MLC standard.
DDEX envisages that it will, at some stage, extend the NewReleaseMessage defined in the Release Notification Message Suite Standard to support the provision of mandates from Record Companies to MLC. No specific timetable for this extension has been agreed. For the time until such an extension has been developed, Record Companies have several options to communicate mandates to MLCs: Either they can use the DeclarationOfSoundRecordingRightsClaimMessage defined in this standard or any exiting format.
7 Message Content Overview (informative)
Each of the messages defined in this Standard conveys a set of data elements from sender to recipient. The following diagrams show these information elements for the various messages. They allow a rapid overview of the different messages for technicians as well as for business process experts of organisations that are to implement the Standard defined herein. The data element names shown in the diagrams below are not the formal names used in the messages as thediagram is intended to provide a quick overview of the data to be provided within the messages. The diagrams are not normative.
Note that one XML Attribute, LanguageAndScriptCode, is only shown on the top-level (message) composites. This attribute is, in fact, present on all composites or elements that might benefit from being coded in different languages and/0r scripts. If placed on a composite, its value applies to all sub-elements (and, potentially, overrides a different LanguageAndScriptCode “further up”. If placed on an element its value applies only to that element. The LanguageAndScriptCode is provided in accordance with IETF RfC 4646.
Also note that dashed lines represent logical relationships between entities. These relationships are represented not but one entity’s metadata physically including the other entity’s metadata but by referencing — using XML Schema’s xs:ID/xs:IDREF mechanism — the linked entity. The “anchors” for these references are not listed in the diagrams below.

8 Message Definition
This Clause contains an overview for each of the three messages in the Main Profile of the Electronic Release Notification Message Suite in a tabular form. The full technical specification is provided in Annexes A (technical description) and B (XML Schema files).
The Standard comprises five messages:
- DeclarationOfRevenueMessage – A Message in the Music Licensing Company Message Suite Standard containing a declaration of Revenue from the Usage of Releases.
- DeclarationOfSoundRecordingRightsClaimMessage – A Message in the Music Licensing Company Message Suite Standard containing details of a SoundRecording.
- RequestSoundRecordingInformationMessage – A Message in the Music Licensing Company Message Suite Standard containing a request for a declaration of SoundRecordings
- RevokeSoundRecordingRightsClaimMessage – A Message in the Music Licensing Company Message Suite Standard in which a claim, typically communicated via a DeclarationOfSoundRecordingRightsClaimMessage, is revoked.
- SalesReportMessage – A Message in the Music Licensing Company Message Suite Standard used by one Music Licensing Company to inform a second Music Licensing Company about unit sales of Releases in electronic or physical formats.
In addition this standard defines a ManifestMessage and re-uses the FtpAcknowledgementMessage defined in DDEX-AMEP.
The hierarchical structure of the messages is provided through indentation. On the Message Header for example, the PartyName is a child of Sender. Thus, a Sender contains a PartyName (plus a PartyId). A second example from the Message Header is the MessageAuditTrail that contains MessageAuditTrailEvents which, in turn, contains a MessagingParty- Descriptor and a DateTime element. All elements that have subelements are printed in bold. The MessageAuditTrailEvents element also shows a second structural feature of the Message Summary: the cardinality. In the case of MessageAuditTrailEvents the entry "1-n" means that each MessageAuditTrail contains one or more MessageAuditTrailEvents. Other possible cardinality entries are: "1" (for: exactly one), "0-1" (for none or one) or "0-n" (for none to multiple). Elements shown in italics are represented in the XML Schema as XML Attributes. In several places within the messages, the Message Sender may need to make a choice between using two or more XML elements. These instances are marked in the tabular representation of the messages below with the keyword XmlChoice. This keyword is not part of the messages; instead exactly one of the “branches” below the XmlChoice keyword has to be used. Each branch is indicated by a capital letter A, B, C, ... Each branch may consist of several sub-elements.
In addition to the tabular description of the message, which should always be read in conjunction with Annexes A and B, additional conformance rules, which go beyond XML Schema validation, are provided where necessary. The general conformance rules for all messages within this Standard are provided in Clause 7.1.
Specific business processes between sender and recipient may require even further conformance rules. These are, however, not part of the Standard and will need to be agreed between business partners. Rules relating to the authority of business partners to unilaterally change the Message Standard in this way are set out in the current version of the Procedures for the Development and Maintenance of DDEX Standards which forms part of the overall governance of the DDEX Standards.
The syntax as well as the semantics of the various elements in the messages is provided in this Clause. They are taken from the current version of the DDEX Data Dictionary as defined through, and maintained in accordance with, the DDEX Data Dictionary Standard.
8.2.1 Schema Validation
A message is conformant to this specification only when it validates against the set of XML Schema files provided in Annex A.
8.2.2 Allowed Value Lists
The allowed values are listed, defined and provided through the DDEX Data Dictionary Standard in accordance with the latest version of DDEX-DICT. Other values are not possible unless by using the mechanism described below:
This Standard does not explicitly list allowed values. The XML Schema files – as provided in Annex A – contain the allowed values at the time of writing of this Standard. Some of the allowed value sets contain a provision to either use a User Defined Value instead of a DDEX-defined value (in that case the MessageSender has to select the value “UserDefined” from the AVS and provide its own value in the XML attribute “UserDefinedValue”) or to augment a DDEX-defined value (in that case the MessageSender may not select the value “UserDefined” from the AVS but shall provide its additional information in the XML attribute “UserDefinedValue”). In either case the Namespace attribute shall be used to indicate where the UserDefinedValue is defined and maintained.
8.2.3 Allowed values for Namespace Attributes
The Namespace attributes can be used to allow message parties to use proprietary value lists.
The allowed value for the Namespace attribute which is recommended to be used is the DDEX Party Identifier of the party controlling the proprietary allowed value, as defined in, and administered in accordance with the latest version of the DDEX Party ID Standard, DDEX-MPID.
8.2.4 Indicating unknown values
When the sender of a message is required to provide a data element but cannot do so, the following values shall be entered:
In fields of type xs:string: “#unknown#” ;
In fields of type xd:date: “9999-01-01”;
In fields of type xs:datetime: “9999-01-01T99:01:01”; and
In fields of type xs:duration: “PT99H01M01S”.
The circumstances under which such behaviour is permissible may be limited in the specific business relationship between message sender and message recipient.
8.2.5 Contratually Mandatiory
The messages defined in this standard contain fields with cardinality “0-1” or “0-n”. Therefore these fields are from the standard’s point of view, optional. Such fields may, however, be mandatory when a DDEX message is sent in a specific commercial context.
In such circumstances, a message is deemed conformant only if and when it contains all the “contractually mandatory” fields as agreed by MessageSender and MessageRecipient.
8.2.6 Schema Version
The only valid value for this field is "mlc/11".
