4. Web services interface
New specification of web services
Synchronious communication via SOAP protocol ver. 1.1, type SOAP-Document
Used for structured data (XML) exchange
Synchronious communication via SOAP protocol ver. 1.1, simplified version
Used for EDI message trasfer in mode client/server only
Ways of communication
client-server – initialization is from clients side. Client systém have to support web services according defined standard.
server-server – inicialization from both sides. Clients systém must have accessible web services according to OTE std. This way is possible to use only for SOAP-Document type of comm.

ETSO Scheduling System (ESS) V3R1
ETSO Acknoledgement Process V5R0
ETSO Status Request V1R1
For communication between OTE – ČEPS and SEPS in area of market couplingare used XML messages according to following ETSO standards:
ETSO Scheduling system ESS – Version 3 Release 1
ETSO Capacity Allocation and Nomination ECAN – Version 4 Release 0
ETSO Acknowledgement Document EAD – Version 5 Release 0
ETSO formats will be implemented in exact format that is published at ETSO web site

8. EDI messages – changes in Upgrade CS OTE
External interface of automatic communication will support EDI (std EDINE with statutory requirements adjustments) for following processes:
Communication in area of measured data
For input in format MSCONS
For confirmation in format APERAK
Communication in area of additional invoicing data for distributors VO (DUF VO)
A scope and form of messages will not differ from current implementation.
Support of other EDI messages will be closed.

12. Parael run current and upgraded CS OTE
Primary system – current system CS OTE that is operated in production till the end of year 2009.
Secondary system for evaluation – upgraded system
Purpose of parael run
It is ment for evaluation and adaptation of upgraded system by market participants.
An optional comparison of results and outputs from upgrade CS OTE

13. Phases of parael run
I. Phase – data processing check (parael data input to both enviroments)
The purpose is evaluation and comparison of modules that have not been modified in scope of upgrade or modules that were modified during a year 2009 in both enviroments. This phase will affect mostly Center of Data Services (processing of measured data, aggregations, reallocation and outputs for subjects of settlement that are input for settlement of imbalance process.)
Cooperation of OTE and Logica
II. Phase – evaluation of external interfaces and new features of upgraded systém with market participants
The aim is to evaluate whether all market participants are all set to go-live (productive run) from Above all in those areas:
Modification of external interfaces
Evaluation of market participants readiness to all amended functionalities and features even possible changes of their processes & systems.
III. Phase – complex operation examination (simulation of production run)
The main target of this phase is complex evaluation of all activities during a trading day (or days) that will include collection of data, their processing and settlement.

Evaluation of all processes in one trading day
Introduction of all new interfaces (web + automatical communication)
Participants
Simulation of complex operations
Trading (all markets), registration of diagrams, supplier change process, measured data …
Open for all market participants (the more contributors the better evaluation)

16. Access items for the parael run
To establish an encrypted channel for automatic communication during KV2 and KV3 phases we offer following variants of certificates:
SW certificates that will be valid after parael run and will be used for testing/training enviroment – they’ll be handed out free of charge. Be warned that sw certificate has possible security breach of copying this access item and with the knowledge of a password it can grant the access to historical data stored within the testing / training system.
HW certificates that will be used for testing / training after period of parael run – those certificates will be issued on standard commerce terms either from OTECA or I. Certification authority.
Usage of currently issued testing certificates – some of participants have HW certificates for testing purposes today. Those certificates can be used during testing phases KV2 and KV3 and all parael run.
