This section explains the specific conditions for the use of InfoCores (“Specific Conditions of Use”) and, as such, these will be exclusively applicable to the Obligated Entities required to submit information to CORES and the persons authorized by the former to access the application on their behalf (“Authorized Users”). 

In all instances not covered under these Specific Conditions of Use, the previous General Conditions will apply. 

The request for access to InfoCores and the authorization of use by an Obligated Entity implies acceptance and commitment to comply with the General Conditions, the Specific Conditions of Use and the Technical Manual of InfoCores. This document can be downloaded once the application has been accessed, and should be read by all Authorized Users.

1. Registration and type of Authorized Users 

Authorized Users may be the representatives of the Obligated Entity (authorized to send messages and conduct other operations in their name) or users with read-only access (who will only employ the application to view and consult the information on behalf of the Obligated Entity). 

The registration of Authorized Users with InfoCores will be conducted via an identity verification process and, as applicable, proof of representation which will require the submission of certain documents (powers of attorney, DNI or National ID document, passport or equivalent documentation etc.). In addition, the Authorized User must be in possession of a digital certificate which permits access to the aforementioned platform. 

The Obligated Entities and their Authorized Users will have responsibility for the following:

  • The truth and accuracy of the information provided, expressly declaring that all documents supplied are authentic and relate to their current situation.
  • To maintain valid the digital certification necessary to make use of InfoCores.

In addition to the above, the Obligated Entities have sole responsibility for managing and updating their lists of representatives and read-only users. In this regard, each Obligated Entity is legally responsible for updating such information every time a member of their staff is added or removed from the list of authorized InfoCores users.

2. Duty of confidentiality 

The Obligated Entities and their Authorized Users agree to maintain the strictest confidentiality in regard to the information they access via InfoCores which might be subject to such an obligation.  

In this regard, CORES expressly reminds its users that any significant aspects related to the commercial situation of the Obligated Entity will be considered strictly confidential in terms of the individualized data from the company, in accordance with article 5.4 of Royal Decree 1716/2004 of the 23rd July and the Resolutions of the General Directorate of Energy and Mining Policy, of the 29th May 2007 and the 15th December 2008.

3. Obligations of the Obligated Entities and Authorized Users 

The Obligated Entities and Authorized Users expressly agree to make proper use of the platform, and in particular:

  • To not permit third parties to use the digital certificate allowing access to InfoCores. Custody of the latter corresponds to the title holder of the certificate, who will answer to CORES for any access to the application made by third parties. In this regard, CORES advises its users that all operations performed on InfoCores will leave a trace or log which can detect the time of access, the actions taken and the resources consulted. Likewise, all failed attempts to access the platform will be recorded. This information may be analyzed by CORES technical services, and the detection of any anomalies in application use can result in the automatic cancellation of the access rights of the Authorized Users involved.
  • To immediately notify CORES of any incident detected in relation to the use of the platform and, in particular, any situation which might affect the security of the same. The notification of such incidents should be made in the manner described in the Technical Manual. 
  • To follow the protocols listed in the Specific Conditions and the Technical Manual of InfoCores whenever they perform operations via the application, otherwise any resulting damages caused to either CORES or other parties will be the legal responsibility of the Obligated Entity and/or the Authorized User.

4. Cancellation of InfoCores registration 

Authorized User registration will be cancelled in the following cases: 

  • In the event that the Authorized User terminates their employment or collaboration with the Obligated Entity.
  • In the event that the powers granted to the Authorized User by the Obligated Entity are revoked for whatever reason.  
  • In the case of temporary leave which makes it impossible for the Authorized User to continue their normal access and use of the platform, leading to their duties being performed by another person.  
  • On the decision of the Obligated Entity, which is entitled to change its list of persons authorized to use InfoCores on their behalf, or as their representatives, at any time.  
  • On the decision of CORES, in the event that any anomaly or illegitimate use of InfoCores is detected. In this event, CORES will notify the decision adopted to the Obligated Entity and the reason for the cancellation, obliging the Obligated Entity to rectify any deficiencies and/or appoint new authorized personnel.

Cancellation may be requested, in the manner described in the InfoCores Technical Manual, either by the user themselves or by the Obligated Entity. When the Authorized User whose registration is cancelled is the only representative of the Obligated Entity, the Obligated Entity will not be able to submit any informative reports via InfoCores until a new Authorized User or representative has been appointed. 

In the event that the Obligated Entity fails to notify the cancellation of the user’s registration, CORES will be exempt from all liability towards third parties.
