1 Introduction

1.1 Description

OpenNumismat is a handy and reliable application designed for collectors of coins and coin collectors, to create a numismatic collection.

With OpenNumismat you will be able to create, organize, and manage your own catalogs of coins with detailed descriptions and photos for each item.

OpenNumismat is distributed in full absolutely free. The source code is licensed under the GPL-3.0 and available at GitHub.

Official website is located at http://opennumismat.github.io.

1.2 Features of the implementation

OpenNumismat is based on the PyQt library with the SQLite database engine to store the data collection, which allowed to achieve lightness and responsiveness of the interface and cross-platform.

A complete list of the used components and libraries is available here.

Icons used in the interface, based on the LED Icon Set v1.0, Soft Scraps Icons by deleket and Flag icons.

Translation of the interface implemented by enthusiasts using the service Transifex. Thank you for the help!

Text fields (such as Subject, Features, Description, Note) support links:

For paste link to a local file you can drag'n'drop or copy-paste file into text field in Edit dialog.

3.1.1 Editing Images

The application supports up to 11 images of each coin.

The following image formats are supported: BMP, GIF, JPEG, PNG, TIFF, WEBP, JPEG2000, PBM, PGM, PPM, XBM, XPM. Images are saved in JPEG format. Large images are compressed so that the maximum side does not exceed 1024 pixels (you can change it in the Settings dialog).
To insert or change an image, right-click on the field and select one of the drop-down menu items:

  • Load... - select image from file on disk;
  • Save as... - saves the image to a file on disk;
  • Rename... - set a unique name for the image that will be displayed in the tooltip of the image panel (see 4.2);

4 View Coins

4.1 Table of coins

The Table of coins is the central element of the application, serves to display coin data according to those selected with the settings.

The number and location of fields can be set in the List->Select columns... menu or by right-clicking on the table header and selecting Select columns....

In the opened dialog, it is necessary to mark the fields of interest. Dragging the names of fields with a mouse can change the location of the fields relative to each other. You can also drag field headers directly into the coin table. Clicking on the field header sorts the table according to the selected field.

You can control the width of a column in a table by expanding the border of the column heading with the mouse or by right-clicking on the header and selecting Adjust size.

4.2 Image Panel

This panel displays images tied to the coin. At the bottom of the panel are checkboxes allowing you to control the number of simultaneously displayed images.
Double-clicking opens the image in the standard image viewer of your OS. When you hover your mouse over an image, a unique image name is displayed, if it was specified when editing the coin.

4.3 Filter

Using the menu in the column headings of the table, you can filter coins by the value of the fields.

The Filter menu contains all column values. Marked values will be displayed, the rest will be hidden. To mark all items or remove marks from all values, select (All). At the top of the menu is a field that allows you to filter out the menu values.

To reset all filters in the current list, click the Clear all filters button on the toolbar:

4.4 Tree

The tree on the left side of the application window allows you to group coins by field values. When selecting a tree element, the coins corresponding to the selected value are displayed in the table.

To customize the tree, right-click on the tree element and select Customize tree...:

In the opened dialog you can change the structure of the tree by dragging the elements with the mouse. Items that are dragged from right to left are added to the end of the tree. Dragging from left to right removes items from the tree. To merge two fields (for example, Value+Unit), hold down the Ctrl key while dragging.

4.5 Lists

The lists allow you to have several independent collection views. Each list stores its own settings for fields, columns, filters and tree. This allows the lists to be used as permanent filters.

Add a new list by clicking on the List->New... menu or by double-clicking on the list panel (from the empty space next to the headings of the existing lists) and entering the name of the new list. You can also create a copy of the existing list by right-clicking on the source list and selecting Clone.

You can change the name of the list by selecting the List->Rename... menu or by right-clicking on the list title and selecting Rename....

Closed lists are not deleted and are available in the List->Open menu. To permanently delete private lists, select the List->Open->Remove all menu.

4.6 Status Bar

At the bottom of the application window there is a status bar showing the name and path to the collection file, the total number of coins in the collection and in the current Table of coins, the number of coins in the selected group.

5 Managing a collection file

The collection file is a regular file with the extension .db and stores all data about the collection including images other than references (see 7). You can copy, move, delete and rename it by means of your OS.

5.1 Creating/Opening

To create a new collection, select the menu File->New.... In the dialog that opens, select the location and name of the new collection file.

To open an existing collection file, select the File->Open... menu and select the desired file. You can also associate collection files (for example, if you select the appropriate option when installing the application) and open them automatically when you "call" from the file manager.
The File menu displays up to 5 recently opened collections available for quick opening.

5.2 Backup

To prevent data loss of the collection due to hardware, software, human errors, as well as the work of malicious programs, it is recommended to perform a backup. To create a backup copy of the collection, select the menu File->Backup. This will create a copy of the current collection with the date and time stamp added (for example, demo_171025115112.db for the copy made at 11:51:12 on 25/10/2017) in the directory specified in the settings. To restore the data, just rename the backup file by deleting the time stamp. You can also copy the collection file using your OS.

Note: It is recommended to store backups on a physical medium other than the worker. Choosing a cloud storage, such as Dropbox, can be a good option. It is also important to make backup copies on a regular basis, before or after making a large number of changes (see 8.4).

5.3 Vacuum

In view of the peculiarities of SQLite implementation, which provides storage of collection data, memory is not automatically released when data is deleted in the collection file. Over time, this can lead to an increase in the size of the collection file, its fragmentation and slowdown of the application. If necessary, you can reduce the size of the collection file by releasing unnecessary "empty" space by selecting the File->Vacuum menu.

5.4 Password

In the menu File->Set password... you can set the password that will be requested each time the collection is opened.

Note: data encryption is not carried out, so the password protection cannot be considered complete.

5.5 Synchronization

Changes made in multiple copies of a collection file can be merged safely with the menu File->Synchronize....

The most important properties of the synchronization algorithm:

  • All new entries will be added (detected by Created field) to opened collection.
  • Entries with the same value of ID and Created field will be updated when Updated field value is less in opened collection.

5.6 Importing

OpenNumismat allows you to import data from collections creted in another software (MS Excel, CoinManage, Collection Studio and Tellico) or sites (Colnect, Numista and uCoin.net).

For importing from MS Excel select the menu File->Import->Excel and select the source file. After that, the dialog for assigning fields with the first 10 coins from the source file will be opened:

6 Reports

6.1 Generating reports

The application supports the generation of reports on templates. You can edit existing ones or create your own report templates.
The generated report can be printed or saved in HTML, PDF, MS Word formats from the Preview dialog.

To create a report, you need to select the coins for which data will be included in the report and open the Preview dialog by selecting the Report->Report... menu:

In the Preview dialog, you can select a report template (the left list on the toolbar), control the preview mode, and print or save the report to a file of the desired format (right buttons on the toolbar).

Note: Preview dialog use old library for generating HTML. So reports in preview may be corrupted and do not match the view in modern browsers. Also it may crash when generating large reports (more than 100 coins). For viewing and printing you can use Quick report (see 6.2) for open report in your browser.

6.2 Quick Report

By selecting the Report->View in browser menu, you can quickly view the report for the selected coins in HTML format.

For a quick report, used the template set in the Settings dialog as the Default template.

6.3 Editing Templates

The engine for generating template reports is based on the open-source Jinja2 library.

User templates should be placed into Documents folder (usually C:\Users\user\Documents\OpenNumismat\templates). Each template is in a separate subfolder, the name of which is used as the template name.

The reports are generated in UTF-8 encoding and, accordingly, the templates should be in the same encoding. Therefore, for editing templates it is recommended to use, for example, Notepad++.

Attention: when deleting, reinstalling or updating the application, user templates can be lost. Always back up your templates, if you make changes to them, before these actions.

6.4 Report template examples




6.5 Exporting the Table of coins

OpenNumismat allows you to save the current Table of coins with all applied filters and sorting in a separate file in MS Excel, HTML or CSV format (Note: in the current implementation, images are not exported).

You can export the Table of coins in the menu Report->Save current list.... In the opened dialog select the file name, the required format and save the file.

6.6 Statistics

Also for create any diagram and calculating statistics you can use MS Excel. Copy coins that you need from OpenNumismat to MS Excel or export Table of coins to MS Excel file (see 6.5) and use its functionality.

6.7 Summary

7 References

References make it easy to enter data when editing a coin, and also add icons (such as flags) to the data display. References are available for the following fields: Region, Country, Period, Ruler, Unit, Mint, Series, Grade, Material, Shape, Quality, Edge, Rarity, ObvRev, Type, Defect, Place (purchase or sale).

Editing references is available from the Edit dialog:

or from menu Reference->Edit...:

Right-clicking on the entry in the directory opens access to adding or deleting the item's icon:

References for Country, Period, Ruler, Unit, Mint, Series is a cross-references and their updating is available only if you select the value of the base field that exists in the reference. For example, to add a new mint, you should first select an existing country.

The Sort check box sorts all the entries in the directory, otherwise all items will be displayed in the order they were entered.

To quickly fill references with entered data from the collection, select the Reference->Fill from collection menu.

By default, references are stored in a separate file with a .ref extension, which can be copied, renamed or deleted by means of your OS. The path to the references file can be specified in the Settings dialog.

Also you can attach current reference to a collection file. Select Reference->Attach current reference for attaching or Reference->Detach current reference for remove reference from collection and use default from Settings.

8 Settings

The Settings dialog allows you to configure the appearance and behavior of the application. To open the dialog, select the menu File->Settings:

8.1 Fields

The Fields panel of the settings dialog allows you to rename and remove part of the collection fields from the interface. In this case only the selected fields will be displayed in the program interface, but the data will be saved for all fields.

8.2 Acceleration of storage

The SQLite database engine have a multiple settings that affect the speed and reliability:

  • Reliable - all changes will be guaranteed to be saved;
  • Fast - changes can be lost when power is turned off during operation (recommended for most cases);
  • Extra fast (dangerous) - recommended when you perform a large number of changes, provided that you perform a backup.

8.3 Images count by default

Default images count in Image panel.

8.4 Autobackup

You can enable autobackup. This feature will make backups after changing specified count of records.
