General outline of SDN directory management
Cooperation NODC <=> national partners:
•
•
•
NODC chooses (if needed) a provided method of
maintenance: XML files via MIKADO or other tool, or
via CMS
Role NODC: => National focal point-coordinate the
overall mngt activities
–
–
–
–
–
Providing assistance in metadata preparation
Collating new records
Quality control of new metadata descriptions
Distributing to portal in case of XML files
Contact with central directory managers
Role Institutes: => Support activities
– Providing new entries
– Complete the information
– Update existing
information.
[email protected] – www.seadatanet.org
Available tools to submit/create new and update
existing records
• Online maintenance by NODCs via Content
Management System
=> EDMERP, EDMO, CSR
• XML export from a partner to the pan-European
directory
– Mikado manual => EDMED, EDMERP, CSR (,EDIOS)
– Mikado automatic for XML export from local system
=> Most relevant for CDI

Metadata Format
•
•
•
The ISO 19115 content model is the basis for the XML formats and related
schema (XSD).
Use of codes from the Common Vocabularies
Use of organization codes from EDMO
Vocabularies
•
•
•
•
•
Use of SeaDataNet common vocabularies for platform types, parameters,
instruments etc. in all directories
Use of EDMO as organization vocabulary
EDMERP as „project vocabulary“
All available as webservices to enable constant accessibility of latest version
SDN Vocab Service :

Management of record identifiers
All systems have to generate unique record identifiers
• For the vocabularies uniqueness is very important for
reference to correct terms. No changes of codes allowed.
• For CDI records the local id is the communication link
between portal and local system. Ordering system works on
this.
• For the other directories, when updated via Mikado-XML, the
local identifier is important. It is the key for the central
system to recognize updates of the same record.
=> Local systems have to take this into account and store
local id‘s!

Management of EDMO
Maintenance
• Updating via CMS forms:
org
org
http://seadatanet.maris2.nl/vu_organisations/we
lcome.asp
• Access only for NODC‘s
• New records only to be created via
request from NODC to MARIS
(governance is strict, because
EDMO is vocabulary)
• When national institute misses
organisation in EDMO during work
=> request to NODC
• Available as webservice (export
only) for use in local systems and

Maintenance
Option 1:
• Editing via CMS forms
• Access for NODC‘s with national
master account
• NODC may create sub-accounts
for other institutes in their
country (EDMO)
• New records to be created
directly in CMS by NODC
• Sub-accounts can also
edit/create new, but this will
have to be checked by NODC
before activating

Practice EDMO
Use of EDMO CMS
For NODC:
• Webpage: http://seadatanet.maris2.nl/vu_organisations/pwelcome.asp
• Check the list of marine institutes from your country:
– If records not complete (Location, URL, etc!) => add information
– If you find some institutes not listed in EDMO => Request new record to
be added (MARIS)
For other partners:
• Go to current EDMO collection of your country via:
http://www.seadatanet.org/Metadata/EDMO
• Look up details of organisations (your own and others) and if needed
request edit of the EDMO record at NODC

Practice EDMERP- Use of EDMERP CMS
•
•
Webpage CMS: http://seadatanet.maris2.nl/vu_edmerp/pwelcome.asp
Discovery: http://seadatanet.maris2.nl/v_edmerp/search.asp
Exercise:
• Log in to CMS
• Create new (international) project coordinated by an organisation from your
country
• Edit all fields as well as possible
• Add partner organisations (also from other countries!)
• IF needed: Request new EDMO record to be added (MARIS)
• Add details to new EDMO records
Alternative:
• Look up current collection of projects
• Check if project really is coordinated by an institute from your country
• Look up other details for the project and add all partner organisations
• IF needed: Request new EDMO record to be added (MARIS)
• Add details to new EDMO records
