+# Predictalytics – Umsetzungsplan (Phase 1 & 2 + Storage-Optimierung)
+
+> **Wie wir das nutzen:** Wir arbeiten diese Liste Stück für Stück ab. Erledigte Punkte werden von `[ ]` auf `[x]` gesetzt. Reihenfolge ist absichtlich so gewählt, dass spätere Schritte auf früheren aufbauen — nicht einfach querbeet abhaken, siehe Abschnitt "Empfohlene Reihenfolge" ganz unten für die Kurzfassung.
+>
+> Phase 3 (Monetarisierung: Auth, Multi-Tenant, Billing) ist bewusst **nicht** Teil dieses Plans.
+
+---
+
+## 0. Vorab-Bugfund (betrifft Phase 1 direkt)
+
+Beim Review ist aufgefallen, dass `TraderAnalyticsWorker.CalculatePnL` **jeden Trade, der kein `Buy` ist, wie ein `Sell` behandelt** (`else pnl += t.Amount`). Das ist falsch für `Split`, `Merge`, `Redeem`, `AddLiquidity`, `RemoveLiquidity` — das sind keine gewöhnlichen Verkäufe. Dieser Fix gehört zwingend in die neue PnL-Engine (siehe A1/A6), nicht als Extra-Task.
+
+---
+
+## Phase 1 – Kernanalytik korrigieren
+
+### A1. Positionsbasierte PnL-Engine
+- [ ] Entscheidung dokumentieren: **Average-Cost-Methode** statt FIFO (einfacher, und – wichtig – kompatibel mit späterer Trade-Kompaktierung in Abschnitt C, weil Average-Cost nur Gesamtstückzahl & Gesamtkosten braucht, keine Einzel-Trade-Reihenfolge)
+- [ ] Neue Domain-Struktur `TraderPosition` (TraderId, MarketOutcomeId, SharesHeld, AvgCost, RealizedPnl, zuletzt aktualisiert) — inkrementell fortschreibbar statt bei jeder Berechnung die komplette Trade-Historie neu zu scannen
+- [ ] Buchungslogik je `TradeSide` sauber definieren:
+  - [ ] `Buy`: Shares += Size, AvgCost neu gewichten
+  - [ ] `Sell`: RealizedPnl += Size × (Price − AvgCost), Shares −= Size
+  - [ ] `Redeem` (Marktauflösung): RealizedPnl += verbleibende Shares × (1 oder 0 je nach Gewinn-Outcome − AvgCost), Shares = 0
+  - [ ] `Split` / `Merge`: als neutrale Positionsumwandlung behandeln (kein PnL-Effekt), nicht wie `Sell`
+  - [ ] `AddLiquidity` / `RemoveLiquidity`: getrennt von Trading-PnL betrachten (eigene Kategorie, fließt nicht in "Trading-Skill"-Bewertung ein)
+- [ ] Unrealisierten PnL für offene Positionen berechnen: `Shares × (MarketOutcome.CurrentPrice − AvgCost)`
+- [ ] Gesamt-PnL = realisiert + unrealisiert (ersetzt `OverallPnL`, `PnL30d/7d/24h` Felder in `TraderAnalytics`)
+- [ ] Prüfen, ob wir zusätzlich/alternativ Polymarkets eigenen `/positions`-Endpoint (`GetTraderPositionsAsync`, liefert `CurrentValue`/`PercentPnl`) als Plausibilitäts-Check oder sogar als primäre Quelle für **offene** Positionen nutzen (aktuell komplett ungenutzt)
+- [ ] `CalculatePnL`-Bug aus Abschnitt 0 im Zuge dessen mit erledigen
+
+### A2. Win-Rate korrekt berechnen
+- [ ] Win/Loss ist **pro Markt**, nicht pro Trade, definiert: ein Markt zählt als "Win", wenn der realisierte PnL aus diesem Markt (nach Redeem/vollständigem Exit) positiv ist
+- [ ] `WinRate = Anzahl gewonnener Märkte / Anzahl abgeschlossener Märkte` (offene Positionen zählen nicht mit)
+- [ ] Placeholder `return 0;` in `TraderAnalyticsWorker.CalculateWinRate` ersetzen
+
+### A3. Deep-Dive-Kennzahlen mit echten Werten füllen
+- [ ] **Voraussetzung klären:** Für Entry/Exit-Qualität und Timing-Accuracy brauchen wir eine **Preis-Historie** pro `MarketOutcome`, nicht nur den aktuellen Preis (`CurrentPrice`). Aktuell existiert keine Historisierung.
+  - [ ] Prüfen, ob Polymarkets CLOB-API einen Preishistorie-Endpoint (`/prices-history`) hergibt, den wir zum Backfill nutzen können
+  - [ ] Falls ja: neue Tabelle `MarketOutcomePriceSnapshot` (MarketOutcomeId, Timestamp, Price) einführen, periodisch befüllt (z.B. durch bestehenden `MarketSyncWorker`/`MarketHistoryWorker` erweitern)
+- [ ] `AvgHoldDurationHours` echt berechnen: gewichtete Haltedauer zwischen Einstieg (Buy-Zeitpunkte, gewichtet nach Größe) und Ausstieg (Sell/Redeem) pro Position
+- [ ] `EntryQuality`: Einstiegspreis im Vergleich zur nachfolgenden Preisentwicklung (z.B. Perzentil des Einstiegspreises innerhalb eines Zeitfensters danach)
+- [ ] `ExitQuality`: analog für Ausstiegspreis
+- [ ] `TimingAccuracy`: z.B. Anteil der Trades, die kurz vor einer für den Trader günstigen Preisbewegung platziert wurden
+- [ ] Hardcodierte `50`-Neutralwerte in `AnalyticsService.PerformDeepDive` entfernen
+
+### A4. Strategie-Klassifikation verbessern
+- [ ] Zusätzliche Signale einbeziehen statt nur "Ø-Größe" und "Hedging-Rate":
+  - [ ] Verteilung der Haltedauern (kurz/lang, Varianz)
+  - [ ] Diversität der Marktkategorien
+  - [ ] Anteil der Trades kurz vor Marktauflösung vs. früh im Marktleben
+  - [ ] Nutzung gegenläufiger Positionen (Arbitrage-Muster über mehrere Outcomes/Märkte)
+  - [ ] Trade-Größen-Varianz (regelmäßig gleich große Orders = evtl. automatisiert)
+- [ ] Überlegen, ob `StrategyType` als reines Einzel-Enum ausreicht oder ob wir zusätzlich Mehrfach-Signale/Tags parallel speichern (z.B. "primär Hedger, aber auch Whale-Größenordnung") — Enum bleibt als Primär-Tag, Zusatzsignale als eigene Felder/Scores
+- [ ] Sicherstellen, dass nicht der Großteil der Trader dauerhaft bei "Unknown" landet (aktuell strukturell der Fall)
+
+### A5. Copytrading-Eignungs-Score (neu)
+- [ ] Neue Metrik-Dimension definieren, unabhängig vom bestehenden `PriorityScore`:
+  - [ ] **Liquiditäts-Fit**: durchschnittliche Positionsgröße im Verhältnis zur Marktliquidität/zum Volumen zum Handelszeitpunkt (Slippage-Risiko für Nachahmer)
+  - [ ] **Reaktionsfenster**: wie viel Zeit bliebe einem Copytrader realistisch zum Nachziehen (Trader mit Sekunden/Millisekunden-Kadenz sind nicht kopierbar)
+  - [ ] **Frequenz/Konzentration**: sehr hochfrequente/bot-artige Trader senken den Score automatisch
+  - [ ] **Track-Record-Länge & Konsistenz**: mehr abgeschlossene Märkte mit konsistent positivem PnL = höheres Vertrauen
+- [ ] Kombinierten `CopytradingScore` (0–100) berechnen und persistieren (neues Feld auf `TraderScore` oder eigene Entity `TraderCopytradingProfile`)
+- [ ] Im Dashboard/API sichtbar machen (getrennt von der bisherigen "Priorität", da unterschiedliche Fragestellung: *gut* vs. *kopierbar*)
+
+### A6. (siehe Abschnitt 0) TradeSide-Bugfix in PnL-Berechnung
+- [ ] Erledigt sich durch A1, hier nur als Häkchen zur Nachverfolgung
+- [ ] Kurzer Änderungsvermerk/Commit-Hinweis, damit klar ist, dass dieser Bug bewusst behoben wurde
+
+---
+
+## Phase 2 – Robustheit & Wartbarkeit
+
+### B1. EF Core Migrationen einführen
+- [x] Aktuellen Ist-Stand des Schemas exakt erfassen (inkl. aller manuellen `ALTER TABLE`-Patches aus `DependencyInjection.cs`) — abgeglichen, Entities/`OnModelCreating` deckten den Patch-Stand bereits vollständig ab
+- [x] Erste **Baseline-Migration** erzeugt (`20260701102311_InitialBaseline`, in `src/Predictalytics.Infrastructure/Migrations/`), entspricht exakt dem aktuellen Schema
+- [x] `EnsureCreatedAsync` + handgeschriebene `ExecuteIfColumnMissing`/`ALTER`-Helfer aus `DependencyInjection.cs` entfernt, durch `db.Database.MigrateAsync()` ersetzt (Platform-Seed bleibt als `INSERT IGNORE`)
+- [ ] **Offen (manueller Schritt durch Nutzer):** Live-DB per SQL als "bereits migriert" markieren (`__EFMigrationsHistory`-Tabelle + Insert für `20260701102311_InitialBaseline`), da die Tabellen dort schon existieren und nicht per `CreateTable` neu angelegt werden dürfen. SQL wurde im Chat bereitgestellt, Ausführung liegt beim Nutzer (bewusst nicht automatisch gegen die produktive Remote-DB ausgeführt)
+- [ ] Alle künftigen Schemaänderungen aus Phase 1 (z.B. `TraderPosition`, `MarketOutcomePriceSnapshot`, `TraderCopytradingProfile`) als reguläre Migrationen anlegen — **dieser Task sollte vor A1 abgeschlossen sein**, damit wir dort nicht wieder manuell patchen
+
+### B2. Secrets-Management (Release-Vorbereitung, kein akuter Risikofall)
+> Software läuft aktuell nur lokal, kein Fremdzugriff — Passwort bleibt vorerst wie es ist, keine Rotation nötig. Dieser Punkt ist reine **Vorbereitung**, damit das Projekt bei Bedarf später auch ohne die aktuellen Secrets veröffentlicht/geteilt werden könnte, ohne den Code nochmal anfassen zu müssen. Dadurch niedrigere Priorität als vorher angenommen — kann später in der Reihenfolge stehen.
+- [ ] Produktiven MySQL-Connection-String aus `appsettings.json` in Umgebungsvariablen/User Secrets verschieben
+- [ ] `appsettings.json` im Repo künftig nur Platzhalter/Dev-Default enthalten, damit ein Klon des Repos ohne die echten Zugangsdaten lauffähig bleibt (mit eigener lokaler DB)
+- [ ] Keine Passwort-Rotation nötig, solange rein lokale Nutzung
+
+### B3. Scoring-Pipeline entkoppeln
+- [ ] `PollingWorker` soll **nicht** bei jedem 60-Sekunden-Zyklus alle Trader neu bewerten
+- [ ] Nur Trader neu bewerten, die seit letzter Berechnung neue Trades bekommen haben (Dirty-Flag oder Vergleich `LastTradesUpdatedAt` vs. `TraderScore.CalculatedAt`)
+- [ ] N+1-Datenbankzugriffe in `ScoringService.RecalculateAllScoresAsync` durch Batch-Queries ersetzen
+- [ ] Eigenes Intervall für volle Neuberechnung/Ranking (z.B. alle 15 Min) getrennt vom reinen Trade-Polling (60s)
+
+### B4. Testabdeckung für die kritische Logik
+- [ ] Neues Testprojekt (z.B. `Predictalytics.Application.Tests`) anlegen — aktuell existiert **kein einziges** Testprojekt
+- [ ] Unit-Tests für die neue PnL-Engine (A1) — insbesondere Grenzfälle: nur offene Position, nur geschlossene Position, Split/Merge, Redeem-Verlust vs. -Gewinn
+- [ ] Unit-Tests für Win-Rate (A2)
+- [ ] Unit-Tests für Deep-Dive-Kennzahlen (A3) und Copytrading-Score (A5)
+- [ ] Diese Tests idealerweise **parallel zu A1–A5** schreiben, nicht erst am Ende nachziehen
+
+### B5. Kleine verwandte Aufräumarbeit
+- [ ] Log-Rotation/Retention der Serilog-Datei-Sinks (`WinFormsHost/logs`) prüfen — wächst potenziell unbegrenzt, ähnliches Prinzip wie die DB-Speicherplatzfrage unten
+
+---
+
+## Datenbank-Speicherplatz-Optimierung
+
+### C0. Kritische Bewertung deiner beiden Ideen (überarbeitet nach Diskussion 2026-07-01)
+
+**Neue Rahmenbedingungen, die die Bewertung ändern:**
+- Alle Rohdaten sind jederzeit erneut abrufbar — über Polymarkets `/activity`-Endpoint ([Doku](https://docs.polymarket.com/api-reference/core/get-user-activity), keine sichtbare Limitierung), im Zweifel über die Blockchain selbst. Wir müssen also **nichts "für immer" sichern** — Löschen ist kein unwiderruflicher Datenverlust.
+- Analyseziel ist laut Auftrag explizit die **aktuelle** Strategie und aktueller Erfolg/Misserfolg, nicht die Historie von vor Jahren. Wir brauchen also gar keine unbegrenzte Detailtiefe — nur genug, um "aktuelles Verhalten" zu charakterisieren.
+- Kern-Einsicht aus A1: Sobald ein Trade in `TraderPosition` (SharesHeld/AvgCost/RealizedPnl) eingerechnet ist, wird die **Rohzeile für die PnL-Fortführung nie wieder gebraucht** — die Position ist bereits die komprimierte Zusammenfassung. Rohdaten braucht es nur noch für die Strategie-/Deep-Dive-Analyse (Haltedauer, Timing, Hedging-Muster), und die soll ohnehin nur das aktuelle Fenster betrachten.
+
+→ Das ersetzt die alte Idee 1 (Archivierung nur inaktiver Trader + Reaktivierungs-Baseline) durch ein einfacheres, einheitliches Prinzip: siehe **C1 – Rollierendes Zeitfenster**.
+
+**Idee 2 (Hochfrequenz-Trader alle 10 Min. aggregieren)** bleibt weiterhin sinnvoll — allerdings in überarbeiteter Form, da die ursprüngliche Beschreibung zu grob war:
+- "Min/Max/Ø Buy-In" ohne Trennung nach Buy/Sell und nach Markt/Outcome zerstört genau die Information, die die PnL-Engine (A1) braucht.
+- Eine feste 10-Minuten-Uhrzeit-Bucket-Grenze für *alle* Trades eines als "Bot" eingestuften Traders würde auch die wenigen möglicherweise bedeutsamen Trades eines Mischtyps mit-aggregieren.
+- Relevant bleibt sie, weil auch *innerhalb* des neuen rollierenden Zeitfensters (siehe C1) ein aktiver Bot enorme Mengen an Trades erzeugen kann — das ist jetzt eine Optimierung fürs "heiße" Fenster, nicht mehr fürs Langzeitarchiv.
+
+→ Vorschlag: **Burst-Erkennung statt starrer Zeit-Buckets** (nur tatsächlich dichte Trade-Sequenzen kompaktieren) und **Aggregation getrennt nach Trader+Markt/Outcome+Seite** mit **VWAP** (mengengewichteter Durchschnittspreis) statt einfachem Durchschnitt — bleibt unter der Average-Cost-Methode aus A1 nahezu verlustfrei für die PnL-Berechnung.
+
+### C1. Rollierendes Zeitfenster statt Archivierung (ersetzt die alte "Idee 1")
+- [ ] Konfigurierbares Retention-Fenster einführen (Default-Vorschlag: 3–6 Monate) — gilt **für alle Trader gleichermaßen**, nicht nur für inaktive. Länge sollte sich daran orientieren, wie weit die Deep-Dive-/Strategie-Analyse (A3/A4) tatsächlich zurückschaut, um "aktuelle Strategie" zu charakterisieren
+- [ ] Reihenfolge pro Trade zwingend einhalten: **erst** in `TraderPosition`/Monats-Aggregat (s.u.) einrechnen und das sicher persistieren, **dann erst** die Rohzeile löschen — rein zeitbasiert, unabhängig davon ob die betroffene Position noch offen oder schon geschlossen ist
+- [ ] Kein Export/Cold-Storage nötig, da jederzeit über die Polymarket-API bzw. im Zweifel über die Blockchain nachladbar — vereinfacht C1 gegenüber der ursprünglichen Idee erheblich (keine Baseline-Felder, keine Reaktivierungs-Sonderfälle)
+- [ ] Optionales, leichtgewichtiges Langzeit-Signal (nice-to-have, niedrige Priorität): ein grobes Monats-Aggregat pro Trader (Monat, realisierter PnL, Trade-Anzahl, Volumen) für einen "war er über Monate hinweg konsistent profitabel"-Trend im Copytrading-Score (A5) — **ohne** Trade-Detailtiefe, nur wenige Kennzahlen pro Monat
+- [ ] Neuer periodischer Cleanup-Job (`TradeRetentionWorker`), der Trades außerhalb des Fensters findet und löscht, nachdem die Voraussetzung (Position/Aggregat aktuell) erfüllt ist
+- [ ] Kurzer Stichprobentest, wie weit `/activity` pro Wallet tatsächlich zurückreicht (bestätigt/verifiziert nur die schon vorliegende Doku-Aussage, geringe Priorität da schon durch Nutzer-Recherche plausibilisiert)
+
+### C2. Kompaktierung von Hochfrequenz-Tradern innerhalb des Zeitfensters (überarbeitete "Idee 2")
+- [ ] Burst-Erkennung statt globalem Zeitraster: Sequenz von Trades mit Abstand kleiner als Schwellwert (z.B. 60s, konfigurierbar) zwischen aufeinanderfolgenden Trades **desselben Traders, Outcomes und derselben Seite (Buy/Sell)** gilt als "Burst"
+- [ ] Mindestlänge für Kompaktierung festlegen (z.B. erst ab 20+ Trades im Burst lohnt sich das)
+- [ ] Bestehende Bot-Heuristik (`intervals.Average() < 10` in `AnalyticsService`) als Ausgangspunkt wiederverwenden/verallgemeinern statt eine zweite, unabhängige Definition einzuführen
+- [ ] Aggregat-Datensatz pro Burst: Anzahl Trades, Summe Size, Summe Amount, Min-Preis, Max-Preis, **VWAP** (nicht einfacher Durchschnitt)
+- [ ] Design-Entscheidung: Aggregat als zusätzliche nullable Spalten auf der bestehenden `Trade`-Tabelle (`AggregateCount`, `AggregateMinPrice`, `AggregateMaxPrice`) statt separater Tabelle — bestehender Code (PnL, Deep-Dive) muss dadurch kaum angepasst werden, ein Aggregat-Datensatz ist einfach ein "Trade" mit `Size = Summe`, `Price = VWAP`
+- [ ] **Reihenfolge beachten:** Diese Kompaktierung erst implementieren, nachdem A1 (neue PnL-Engine) steht und validiert ist — sonst kompaktieren wir Daten weg, bevor wir wissen, was die neue Engine wirklich braucht
+
+### C3. Weitere eigene Vorschläge
+- [ ] **Spaltentypen verkleinern**: `TransactionHash`, `MarketId`, `AssetId` sind Hex-/Dezimal-Strings fester Länge (z.B. `0x` + 64 Hex-Zeichen) — als `BINARY(32)` statt `VARCHAR(66/80)` speichern spart ca. 30–50% Platz auf diesen stark indizierten Spalten und ist schneller
+- [ ] **Tabellen-Partitionierung** von `Trades` nach Monat (`ExecutedAt`) prüfen — erlaubt später das Archivieren/Droppen ganzer Partitionen statt teurer zeilenweiser `DELETE`s
+- [ ] **Materialitätsschwelle**: Mikro-Trades unterhalb eines Betrags (z.B. < $0.50) unabhängig von Bot-Klassifizierung direkt aggregiert erfassen, da sie für Copytrading/Strategieanalyse ohnehin kaum Aussagekraft haben
+- [ ] ~~Kaltarchiv außerhalb der DB~~ — nicht mehr nötig: da Rohdaten jederzeit über die API/Blockchain nachladbar sind (siehe C1), erübrigt sich ein separates Cold-Storage-Export. Nur falls sich die API-Nachladbarkeit später als doch eingeschränkt herausstellt, hier nochmal aufgreifen
+- [ ] **InnoDB-Kompression** (`ROW_FORMAT=COMPRESSED`) für die `Trades`-Tabelle als schneller Zwischenschritt prüfen — kein Datenverlust, kombinierbar mit allem anderen
+- [ ] `Split`/`Merge`/`AddLiquidity`/`RemoveLiquidity`-Ereignisse (siehe A1) ggf. separat und kompakter ablegen, da sie für die Trader-Bewertung meist weniger relevant sind als `Buy`/`Sell`
+
+### C4. Abhängigkeit zu Phase 1
+- [ ] Merksatz: **Erst A1 (neue PnL-Engine) fertigstellen, dann C1/C2 umsetzen.** Sonst laufen wir Gefahr, Rohdaten wegzuoptimieren, die die neue Engine noch gebraucht hätte.
+
+---
+
+## Entscheidung: Frischer Datenbank-Neustart nach Abschluss?
+
+**Neu bewertet (2026-07-01):** Da wir laut C0/C1 ohnehin nichts an Alt-Historie "für immer" brauchen und alles bei Bedarf über die API/Blockchain nachladbar ist, ist ein sauberer Reset am Ende von Phase 1+2 **risikoarm und klar empfehlenswert** — nicht mehr nur eine Option mit Vorbehalt.
+
+### D1. Kurzer Bestätigungs-Check (geringe Priorität, kein Blocker mehr)
+- [ ] Stichprobenartig verifizieren, dass `/activity` für ein bekanntes, lange aktives Wallet tatsächlich vollständig zurückreicht — bestätigt nur die bereits über die [Doku](https://docs.polymarket.com/api-reference/core/get-user-activity) plausibilisierte Annahme, ist kein Show-Stopper mehr für die Entscheidung
+
+### D2. Ablauf des Neustarts
+- [ ] Vollständiges Backup/Dump der aktuellen Datenbank sichern (reine Vorsichtsmaßnahme, wird voraussichtlich nicht gebraucht) und einige Wochen aufbewahren
+- [ ] EF-Migrationen-Baseline + alle Phase-1/2-Schemaänderungen fertigstellen (B1)
+- [ ] Neue leere Datenbank anlegen, Migrationen anwenden
+- [ ] Liste bereits bekannter Trader-Wallets aus dem alten Bestand als Startpunkt für die Re-Discovery übernehmen
+- [ ] Re-Import über die Worker-Pipeline (mit korrigierter PnL-Logik, direkt im Rahmen des neuen Retention-Fensters aus C1) laufen lassen
+- [ ] **Wichtig:** Dieser Schritt kommt ganz am Ende von Phase 1 + 2 — nicht vorher, damit wir nicht zweimal migrieren/importieren müssen
+
+---
+
+## Empfohlene Reihenfolge (Kurzfassung, Stand 2026-07-01)
+
+1. **B1** – EF-Migrationen-Baseline einführen (Fundament für alle weiteren Schemaänderungen)
+2. **A1 + A6** – Positionsbasierte PnL-Engine inkl. TradeSide-Bugfix
+3. **A2** – Win-Rate
+4. **A3** – Deep-Dive-Kennzahlen (inkl. Preis-Historie-Voraussetzung klären)
+5. **A4** – Strategie-Klassifikation verbessern
+6. **A5** – Copytrading-Eignungs-Score
+7. **B4** – Tests (idealerweise begleitend zu 2.–6., hier als Nachhol-Punkt falls übersprungen)
+8. **B3** – Scoring-Pipeline entkoppeln/optimieren
+9. **C1 + C2 + C3** – Speicherplatz-Optimierung: rollierendes Zeitfenster + Burst-Kompaktierung (bewusst erst jetzt, siehe C4)
+10. **D** – Datenbank-Neustart durchführen (ganz am Ende, jetzt als klar empfohlener Schritt statt offener Entscheidung)
+
+(B2 – Secrets-Vorbereitung und B5 – Log-Rotation sind risikoarme Nebenpunkte ohne akute Dringlichkeit, da rein lokale Nutzung; können jederzeit zwischendurch erledigt werden, wenn Zeit ist.)

+  <!--
+    Microsoft ResX Schema
+
+    Version 2.0
+
+    The primary goals of this format is to allow a simple XML format
+    that is mostly human readable. The generation and parsing of the
+    various data types are done through the TypeConverter classes
+    associated with the data types.
+
+    Example:
+
+    ... ado.net/XML headers & schema ...
+    <resheader name="resmimetype">text/microsoft-resx</resheader>
+    <resheader name="version">2.0</resheader>
+    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
+    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
+    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
+    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
+    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
+        <value>[base64 mime encoded serialized .NET Framework object]</value>
+    </data>
+    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
+        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
+        <comment>This is a comment</comment>
+    </data>
+
+    There are any number of "resheader" rows that contain simple
+    name/value pairs.
+
+    Each data row contains a name, and value. The row also contains a
+    type or mimetype. Type corresponds to a .NET class that support
+    text/value conversion through the TypeConverter architecture.
+    Classes that don't support this are serialized and stored with the
+    mimetype set.
+
+    The mimetype is used for serialized objects, and tells the
+    ResXResourceReader how to depersist the object. This is currently not
+    extensible. For a given mimetype the value must be set accordingly:
+
+    Note - application/x-microsoft.net.object.binary.base64 is the format
+    that the ResXResourceWriter will generate, however the reader can
+    read any of the formats listed below.
+
+    mimetype: application/x-microsoft.net.object.binary.base64
+    value   : The object must be serialized with
+            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
+            : and then encoded with base64 encoding.
+
+    mimetype: application/x-microsoft.net.object.soap.base64
+    value   : The object must be serialized with
+            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
+            : and then encoded with base64 encoding.
+
+    mimetype: application/x-microsoft.net.object.bytearray.base64
+    value   : The object must be serialized into a byte array
+            : using a System.ComponentModel.TypeConverter
+            : and then encoded with base64 encoding.
