First steps to web-based tools
→ ‘Diagram’ section in AFOLU-DATA portal
→ Set-up for meta-data collection
→ Successful search for adequate libraries with required functionalities(R h ël J S i t(Raphaël—JavaScript Library).

Which features do we plan?
→ The webtool will be developed in • php technology (CodeIgniter)/Javascript• My-SQL
→ Compliant with W3C standards→ Compliant with W3C standards
Th t l k tThree conceptual eck-stones
→ Flexible editing and ‘customization’→ Online control and help→ Easy import/export of data and graphics

You can close the budget of a pool by adding a stock change:
• Changing input or output• Close budget as stock changes• Let system ‘ignore’

• Let system ignore
Customization of NiNBs
The tool will flexibly allow the addition of (country-specific) N-fluxes. These additions will -if defined with sufficient detail and upon release by the administrator- be available also for subsequent N-budgets.

Exploitation
The tool will contain a reporting area, where the user can generate summary-tables, for example indicating the N-balance of specific sectors.

User-friendliness
→ In cooperation with the partners of the project transparency and user-friendlyness will be checked and improved (e.g. extensive use of 'mouse-over tips', a wiki-page, a discussion-forum or FAQ page or similar, whatever seems most appropriate)
→ (For users support there will be an online user-guide and a quick ticket system to send requests to the administrator.)
JRC-AL: 26.10.2010 – EPNB - Paris - 14
Conclusion
→ The web-based tool will have advantages with respect to the excel tool
• Interactive use of tool more userfriendly• No software incompatibility possible• No software-incompatibility possible• Flexibility vs. harmonization more transparent• Automatic dissemination, if wished
→ JRC is happy to contribute• Hosting of the tool• Supervision of its developmentp p• Contribution to, and assuring consistency with, guidelines
→ Involvement of countries or projects required• Feed-back during development• Ensure that web-tool fulfills requirements• Contract with web programmer
