Data table
| Year | Ontologies | Vocabularies | Data schemes | Total |
|---|---|---|---|---|
| 2023 | 35 | 71 | 0 | 106 |
| 2024 | 48 | 103 | 54 | 205 |
| 2025 | 73 | 154 | 74 | 301 |
| 2026 | 88 | 154 | 74 | 316 |
GENERAL DESCRIPTION
The graph shows the cumulative evolution of semantic resources from year to year, divided by type (Ontologies, Vocabularies, Data Schemas).
VISUALIZATION
The graph presents:
- A stacked bar chart showing the temporal trend of resources
- Three sets of data, one for each type of resource, with distinctive colors:
- Ontologies: blue
- Vocabularies: green
- Data schemes: orange
- Axis X shows the years
- The Y axis shows the cumulative number of resources
FUNCTIONALITY
- Interactivity: you can interact with the chart to view the specific details of each bar
- Legend: allows you to activate/deactivate the display of individual types of resources
- Tooltip: when hovering the mouse shows the detailed values for each year, including the total
- Table view: shows the data in numerical format for a precise consultation
The graph allows you to:
- Analyze the overall growth of semantic resources over time
- Compare the evolution of different types of resources
- Identify periods of particular growth or stasis
- Evaluate the distribution of resources among the different types
Resource holders
| Holder | Ontologies | Vocabularies | Data schemes | Total |
|---|
GENERAL DESCRIPTION
The graph shows the distribution of semantic resources among the various holders over time.
TEMPORARY PERIOD
You can view the data for different time periods:
- From the beginning: shows the total number of resources for each holder
- Last year: shows the resources added in the last year
- Last 6 months: shows the resources added in the last 6 months
- Last 3 months: show resources added in the last 3 months
FUNCTIONALITY
- Selection of holders: you can select which holders to display using the drop-down menu
- Graphic display: shows the distribution of resources in stacked bar chart format
- Table view: shows data in tabular format with totals for each category
- Ordering: owners are ordered from the smallest to the largest according to the total number of resources
Evolution of semantic resources per owner
Distribution of resources among the Owners
Data table
| Month | Ontologies | Vocabularies | Data schemes | Total |
|---|
GENERAL DESCRIPTION
The graph shows the monthly trend of semantic resources by owner and by type of semantic resources.
FILTERS
You can filter the data by:
- Year: Select the year of interest
- Holder: select the holder whose data will be displayed
FUNCTIONALITY
- Graphic display: shows the monthly distribution of resources in stacked bar chart format
- Table view: shows data in tabular format with totals for each category
- Data update: the data is updated only after clicking the "Filter" button
Harvesting times
Running time Harvester
Average harvesting time per year
Data table
| Year | Min(s) | P25(s) | Median(s) | P75(s) | Max(s) |
|---|
The graph shows how long it takes the harvester system to collect and integrate data from contributor public administration repositories, year by year. You can see the minimum, maximum, average values and the statistical distribution of execution times.
How Harvesting Works
The Harvey checks if there is anything new in the GitHub repositories. If it finds changes, download the updated data, analyze it, and update the information in the databases.
What Metrics Mean
Min: minimum execution time recorded
P25: First quartile (25th percentile)
Median: Central value of distribution
P75: 3rd quartile (75th percentile)
Max: maximum execution time recorded
The time it takes to complete the harvesting can change depending on the amount of data to be analyzed, the number of changes found, and the performance of the server. The system is designed to be efficient and fast, avoiding unnecessary operations.
