VoleInfo is built around the match. The goal is not to copy an official page visually; it is to turn official tournament records into a consistent history that can connect a competition, its teams, standings, bracket, sets and player statistics without mixing different categories together.
Official sources come first
When structured official federation or competition data is available, VoleInfo uses it as the preferred source. Official competition websites, continental confederation pages and tournament documents can supplement that structure when necessary. The important distinction is that VoleInfo does not treat a secondary fan page as the canonical authority for a score or roster.
Normalization is the real work
Different organizers can describe the same concept in different ways, and even the same data system can reuse identifiers inside a tournament. A match number such as “1” may be unique in one event but repeated across pools in another. Team names can vary by abbreviation, language or age category. A country’s senior team must never be merged with its U21, U19 or U17 side.
VoleInfo therefore stores canonical countries, teams, competition editions and matches, then maps official source identifiers onto those records. Public URLs are generated from those canonical entities rather than from whatever label happened to arrive in the latest feed.
Live and historical data are different jobs
Active competitions need frequent updates because schedules, scores, sets and standings can change throughout a day. Historical coverage has a different priority: it should grow steadily without competing with live ingestion for the same rate limits and runtime. VoleInfo separates those workflows so an archive backfill cannot make a live match less reliable.
The same principle applies to player statistics. A finished match can exist in the database before its individual player rows have been recovered. Historical player-stat backfill then revisits eligible finished matches, imports the official action rows when available and links historical players to the correct national team.
Why historical rosters are tricky
National-team rosters change during a season. A player who appeared in an earlier match may no longer be listed in the current tournament roster by the time VoleInfo backfills that match. If player statistics were resolved only against today’s active roster, valid historical rows would remain unmatched.
VoleInfo can recover that player from the statistic’s official player relation, associate the federation code with the correct match team and store the historical tournament relationship without turning that player into a current active-roster entry. That allows the match record to become complete while keeping the team page’s current roster clean.
Missing does not mean zero
That distinction matters in volleyball. Zero receptions and no reception data are not the same thing. A missing block-attempt field should not automatically become zero attempts. Treating absence as a real performance value would make both the match page and any downstream rating less trustworthy.
Corrections propagate from the canonical record
Official schedules and results can change after first publication. When the source changes, VoleInfo’s goal is to update the canonical match or competition record and let the connected views follow that correction, rather than patching the home page, competition page and team page independently.
If a reader spots something wrong, the most useful correction report includes the VoleInfo URL and the official source that supports the change. Reports can be sent to contact@voleinfo.com.
Where VoleInfo adds its own layer
The underlying schedules, results and source statistics remain source-published facts. VoleInfo adds value by structuring those facts consistently, connecting them across the product, making brackets navigable, preserving historical context and building clearly labeled derived analysis such as VoleInfo Rating.
That separation is deliberate: readers should be able to tell the difference between “the organizer published this result” and “VoleInfo calculated this analytical score from the available match data.” The full sourcing principles are documented in the Data Policy.
