SCORM Manifest Package (imsmanifest.xml)

What is the SCORM manifest package (imsmanifest.xml)?

The SCORM manifest package is the central file of any SCORM course: an XML document called imsmanifest.xml that defines the structure, content, and metadata of a digital training package. Its role is to act as the “instruction map” that the LMS reads to know how to import, organize, and launch the course. Without this file at the root of the ZIP package, no SCORM-compatible LMS can process the training content.

In corporate training, the imsmanifest.xml is the component that guarantees the interoperability of the SCORM standard: it allows a course created with any authoring tool to run correctly on any compatible LMS, regardless of the vendor. According to ADL Initiative data, SCORM remains the most widely adopted e-learning standard globally, present in more than 70% of active corporate learning management systems.

Structure of the imsmanifest.xml file: main sections

The SCORM manifest follows the IMS Content Packaging specification, which organizes the document into three mandatory sections and a series of root attributes. Understanding this structure allows L&D managers to anticipate how the course will behave in the LMS and diagnose import issues when they arise.

Differences in the manifest between SCORM 1.2 and SCORM 2004

The version of the standard used determines the complexity and capabilities of the imsmanifest.xml file. Although the base structure is the same, there are critical differences that affect how the course behaves in the LMS.

SCORM 1.2 uses the namespace http://www.imsproject.org/xsd/imscp_rootv1p1p2 and the value schemaversion="1.2". Its manifest is simpler: it defines organizations, items, and resources, but does not include advanced sequencing rules. Learner tracking is managed through the cmi.core data model, with fields such as cmi.core.lesson_status for course status.

SCORM 2004 (2nd, 3rd, or 4th edition) incorporates the <imsss:sequencing> element within the manifest, allowing the definition of prerequisites between modules, conditional flows, and progression restrictions. The data model shifts to cmi.completionStatus and cmi.successStatus. For most standard corporate courses, SCORM 1.2 remains the most compatible and widely supported option across LMS platforms; SCORM 2004 is recommended when advanced instructional sequencing is needed.

The role of imsmanifest.xml in corporate e-learning

For L&D teams, the SCORM manifest has direct practical implications for training catalog management:

• Interoperability: ensures the course works on any SCORM-compatible LMS without adaptation. A course created with isEazy Author and exported as SCORM can be uploaded to Cornerstone, SAP SuccessFactors, Docebo, or any other platform without modifications.
• Learning tracking: the manifest declares which SCOs (Sharable Content Objects) make up the course. Each SCO is the minimum tracking unit: the LMS records completion status, score, and time spent separately for each one.
• Portability and reusability: since all course information is contained within the package itself, content can be downloaded and redistributed as SCORM files across different systems or platforms autonomously.
• Launch control: the href attribute of the main resource defines exactly which HTML file the LMS opens to start the course, eliminating ambiguity at the entry point.

Common imsmanifest.xml errors and how to fix them

Manifest issues are the most frequent cause of SCORM course import failures. These are the most common ones in corporate environments:

• “Manifest not found”: the imsmanifest.xml is not at the root of the ZIP, but inside a subfolder. Fix: unzip the package, move the file to the root, and recompress.
• XML syntax error: an unclosed tag, an unescaped special character (e.g. & instead of &), or an incorrect namespace invalidates the entire document. Fix: open the file in an XML-aware editor (VS Code, Oxygen XML) and correct the flagged errors.
• Incorrect resource paths: the href attribute points to a file that does not exist at the indicated path inside the ZIP. Fix: verify that the relative path in the manifest exactly matches the actual file location, respecting uppercase and lowercase.
• Incompatible schema version: the LMS only supports SCORM 1.2 but the manifest declares SCORM 2004. Fix: check LMS compatibility and export in the correct version from the authoring tool.

EMASESA, an environmental services company, used isEazy Author to produce e-learning content in record time, generating valid SCORM packages ready for their LMS with no need for manual technical intervention on the manifest. Discover how they did it →

How to manage the imsmanifest.xml with an authoring tool

Manual manifest editing is feasible for technical profiles, but in practice it represents an unnecessary risk for training departments. Professional e-learning authoring tools generate, validate, and package the imsmanifest.xml automatically with every export.

With isEazy Author, the process is completely transparent for content creators: design the course in the visual editor, select the SCORM version (1.2 or 2004), and the tool generates the complete ZIP package with a correctly structured manifest, properly referenced resources, and LMS communication code already integrated. This eliminates human errors in the XML and guarantees standard compliance from the first attempt. If your team creates training content on a regular basis, knowing how to create a SCORM package step by step with a professional authoring tool saves time and prevents compatibility issues.
