Task: turning the bibliographic data -- from an ad-hoc modeled database in a silo to the data in a standardized metadata repository … heading to the LOD universe

To make local data into a Linked Data dataset --- What metadata standard(s) to follow? What is the minimal set of properties to include to
insure meaningful data sharing? Is there any metadata model or application profile for
my data? What data values to provide – plain text string or
Unified Resource Identifier (URI)? How to encode our data in order to move
from a local database to a Linked Data dataset?
Questions from the data providers:

Example: <Responsible Body>- related data fields from 8 data providers
Various standards were applied
• Everyone uses an ad-hoc in-house
format.

Step 5. Implement the LODE-BD approach in a system
Alternative #1, "Design-time" strategy: go back and change your current ad-hoc model to use the LODE “good practices” model. = > This means some changes to your database and the services that access it.
Alternative #2, "Run-time" strategy: you convert on the fly to a “good-practices” model upon request and leave your ad-hoc model unchanged. => This means adding a conversion service.

LODE-BD principles To promote the use of well-established
metadata standards and the emerging LOD-enabled vocabularies proposed in the Linked Data community;
To encourage the use of authority data, controlled vocabularies, and syntax encoding standards in metadata statements whenever possible;
To encourage the use of resource URIs as data values when they are available;
To facilitate the decision-making process regarding data encoding for the purpose of exchange and reuse;
To provide a reference support that is open for suggestions of new properties and metadata terms according to the needs of the Linked Data community.
