DISCLAIMER-WIP

@@ -0,0 +1,19 @@
+Apache XTable (incubating) is an effort undergoing incubation at The Apache
+Software Foundation (ASF), sponsored by the Apache Incubator.
+Incubation is required of all newly accepted projects until a further review
+indicates that the infrastructure, communications, and decision making process
+have stabilized in a manner consistent with other successful ASF projects.
+While incubation status is not necessarily a reflection of the completeness or
+stability of the code, it does indicate that the project has yet to be fully
+endorsed by the ASF.
+
+Some of the incubating project’s releases may not be fully compliant with ASF
+policy. For example, releases may have incomplete or un-reviewed licensing
+conditions.
+
+If you are planning to incorporate this work into your product/project, please
+be aware that you will need to conduct a thorough licensing review to determine
+the overall implications of including this work. For the current status of this
+project through the Apache Incubator visit:
