Overview

FDO now complies with LGPL v2.1 licensing.

Re-reading the terms of LGPL 2.1, David Ji indicated that LGPL specifies certain limitations when dealing with static linkage to open source libraries.

Please refer to reference - ​https://stackoverflow.com/questions/10130143/gpl-lgpl-and-static-linking.

There are a series of GenericRdbms projects in FDO which are designed and configured as static libraries, e.g. providersCommon, schemaMgr, smLogicalPhysical and so on. It would not be possible to create a new GenericRdbms 3rd party provider without using those static libraries.

The FDO Steering Committee suggests that the FDO project add an exception to the LPGL license to allow 3rd party developers to link to a published set open source projects. This can mitigate misunderstanding and potential legal risks for our developers.

Please refer to https://trac.osgeo.org/fdo/ticket/950 for additional details.

Motivation

Clarify the FDO LPGL license requirements for FDO GenericRdbs? Provider development.

Proposed Solution

Update the FDO License agreement to provide static library exceptions for the following:

Static libraries:

ProvidersCommon.lib
FdoGenericOra.lib
Gdbi_Oracle.lib
GrdSchemaMgr.lib
LockManager.lib
LongTransactionManager.lib
SchemaMgrNew.lib
SchemaMgr_LPNew.lib
SchemaMgr_OVNew.lib
SchemaMgr_PHNew.lib
FDONLS.lib

Corresponding project names:

Utilities\Common\FdoCommon.vcxproj
Providers\GenericRdbms\Src\Fdo\Fdo_Oracle.vcxproj
Providers\GenericRdbms\Src\Gdbi\Gdbi_Oracle.vcxproj
Providers\GenericRdbms\Src\SchemaMgr\GrdSchemaMgr.vcxproj
Providers\GenericRdbms\Src\LockManager\LockManager.vcxproj
Providers\GenericRdbms\Src\LongTransactionManager\LongTransactionManager.vcxproj
Utilities\SchemaMgr\SchemaMgr.vcxproj
Utilities\SchemaMgr\LogicalPhysical.vcxproj
Utilities\SchemaMgr\Overrides.vcxproj
Utilities\SchemaMgr\Physical.vcxproj
Fdo\Unmanaged\Nls.vcxproj

Implications

FDO will adopt a custom licensing scheme that uses LPGL 2.1 as a base but provides the necessary exceptions.
