In the image below, we see the template that generates the above file.

Dynamic Content Integration and interactivity: The seamless integration of code, text, and the representation of information through diagrams, tables, and other visualizations is achieved within a single document. As a result, each file in the medical record gathers all necessary elements and serves as a comprehensive means of presenting information. In the same way, each static document is transformed into a dynamic, interactive experience similar to a traditional user interface in any typical application (Fig.4).

Enhanced Metadata Structure and Complex Data types: In Obsidian MEDILIG, each file type also serves as a metadata type used to describe and present the corresponding entity. For example, in Fig.6, we see the Front-matter placed at the top of every Markdown file that corresponds to a patient visit. The front-matter contains structured data, resembling database entries. However, the connections between files form a graph-like structure (Fig.2), allowing for complex relationships without the need for a separate graph database. This approach simplifies development, as data and presentation are managed in the same file. This reduces system complexity and makes it easier to maintain and adapt.

Data-Content Integration: In the design philosophy of Obsidian MEDILIG, there is no clear separation between data and content. Each file acts as an autonomous unit that contains both structured data (in the front-matter) and rich content, including interactive elements. This contrasts with traditional applications, where data is typically stored separately from its presentation, for example, in a database backend with a distinct frontend for display. In Obsidian MEDILIG, the integration of data and content into a single Markdown file allows for simpler development, easier customization, and a more cohesive user experience.

Data Querying and Manipulation: Based on the Obsidian Dataview plugin and the front-matter of the files created in the patient folder, Obsidian MEDILIG can generate customized dynamic data views (tables) for various purposes, such as patient monitoring lists, statistical data for research, or summary reports for administrative purposes (Fig.7).

Asset Management: The management and organization of multimedia in Obsidian MEDILIG is one of its powerful features. The user feeds the patient’s medical folder with videos, images, audio, or PDF, Word, Excel files, which are automatically recorded with coded names and added to the front-matter of a medical document (Fig.8). These files are displayed inside cards showing their description, capture date, and original filename. The process is very simple, and in this way, the user has at their disposal a complete and integrated network of medical information for the patient.

A graph network of medical information: The use of Obsidian's internal links in medical patient records can prove to be extremely useful and effective in practice (see use of internal links). The system allows for direct and easy interconnection of patient information or the embedding of content (also known as transclusion or Obsidian embedding) from notes or multimedia that are scattered across different files and in specific paragraphs, headers, or any text block. In Obsidian MEDILIG this becomes even easier and faster due to the automatic coded naming of files. Additionally, the use of aliases allows for easy searching and referencing of patients and facilitates rapid access to any file in their medical record. Furthermore, in the interconnected network of medical information in Obsidian MEDILIG, the display and visualization of incoming (backlinks) and outgoing (outgoing links) links (Fig. 9) in each patient record file not only facilitate rapid access to related information, but also highlight non-obvious correlations, thus supporting a holistic approach to medical care and informed decision-making.

Low-Code Development: Thanks to the abundance of plugins, primarily dataview, meta-bind, and templater, Obsidian MEDILIG manages to transform into an extremely flexible platform for Low-Code Development. The dataview allows users to manage and display their data with advanced queries, facilitating the organization and analysis of information. The meta-bind offers the capability of dynamic metadata binding, enabling process automation and the creation of more complex and interactive applications. Finally, the templater allows the creation of templates for frequently used structures and code, accelerating the development process and ensuring consistency in applications. These plugins, in combination, make Obsidian MEDILIG a valuable tool for developers and non-programmers who wish to accelerate the application development process and information management.

Alarm and Reminders: With the integration of the Obsidian Reminder Plugin, it enables automatic creation of reminders for important medical actions, such as scheduling of clinical procedures or follow-up examinations. Through system and application notifications, it informs the user about upcoming or overdue actions via system notifications, helping with timely case management. It offers options for managing reminders, such as confirming completion, postponing, or dismissing, adapting the functionality to the user's needs. In this way, it helps monitor patient compliance with required examinations or treatments, minimizes the risk of omitting important actions due to human error or workload, and ensures that all necessary actions for patient care are performed in a timely manner.

Calendar Time Planner: With the integration of the Obsidian Full Calendar Plugin into Obsidian MEDILIG, the system gains even more powerful capabilities for managing patient visits. Each appointment is linked to the clinical data of the patient's visit. All appointments can be displayed in the calendar in various ways such as monthly, weekly, daily view, or list view and can be managed accordingly. Furthermore, based on the calendar time planner, the doctor can see the list of his patients and various characteristics of those who are scheduled to be seen during the current week.

Interactive computational documents: Obsidian has several similarities to Jupyter notebook and Mathematica notebook. All three tools are examples of interactive computational documents that allow users to create, organize, and share information in a structured way. They use the concept of "notes", pages that can contain formatted text, code, and multimedia. However, while Jupyter and Mathematica focus more on code execution and data representation, Obsidian is more oriented toward information management and creating interconnected notes. The notebook interface has now been widely adopted as the new paradigm for live user interaction.
