Fig.1 STANDARD, OPEN and CLOSED CONCEPTS Fig.2 Example of STANDARD, OPEN and CLOSED CONCEPTS First of all, a concept is a simple version of a Unified Modeling Language (UML) class. The class definition [ 1 ] is adopted to define a concept, namely: a set of objects that share the same attributes, operations, relations, and semantics.

The main parts of the Jupyter Notebooks are: Metadata, Notebook format and list of cells. Metadata is a data Dictionary of definitions to set up and display the notebook. Notebook Format is a version number of the software. List of cells are different types of Cells for Markdown (display), Code (to execute), and output of the code type cells. [23]
For example, one way to represent the notion "The sky has the color blue" in RDF is as the triple: a subject denoting "the sky", a predicate denoting "has the color", and an object denoting "blue". Therefore, RDF uses subject instead of object (or entity ) in contrast to the typical approach of an entity–attribute–value model in object ...
A snippet of Python code with keywords highlighted in bold yellow font. The syntax of the Python programming language is the set of rules that defines how a Python program will be written and interpreted (by both the runtime system and by human readers). The Python language has many similarities to Perl, C, and Java. However, there are some ...
The ISO/IEC 11179 model is a result of two principles of semantic theory, combined with basic principles of data modelling. The first principle from semantic theory is the thesaurus type relation between wider and more narrow (or specific) concepts, e.g. the wide concept "income" has a relation to the more narrow concept "net income".
In the context of Oracle Databases, a schema object is a logical data storage structure. [4]An Oracle database associates a separate schema with each database user. [5] A schema comprises a collection of schema objects.
This type of "translating" from one format to another is often called "metadata mapping" or "field mapping," and is related to "data mapping", and "semantic mapping". Crosswalks also have several technical capabilities. They help databases using different metadata schemes to share information. They help metadata harvesters create union catalogs.
